Abstract |
The Italian Society for Pure and Applied Biophysics (SIBPA) is a scientific association that represents the Italian Biophysics in Europe and in the world. SIBPA collects the Italian researchers with a common interest in the advanced and emerging fields of Biophysics, and dedicates particular attention to the formation of young scientists. In agreement with SIBPA’s mission, the proposed session aims to highlight the interdisciplinary aspect of Biophysics, which facilitates connections between Physics, with its quantitative and modelling approach and its inclination towards the development of innovative techniques and methodologies, Biology and Medicine, which define the open questions to be solved, and Chemistry, which provides molecules and nanostructures useful for specific purposes. In the context of Biophysics, the session will cover both fundamental studies of the biological matter and its processes, and applied studies relying on functional exogenous nanomaterials used in biological environments. Considering the essential relevance of investigating interactions and processes at a molecular level, the session will also expand its horizon beyond, reaching the cellular and tissue level. Wide visibility will be ensured for both theoretical and experimental methods, especially those based on the use of tailored nanostructures for intracellular imaging and sensing, and advanced microscopy techniques. The invited speakers (four, two for each slot) perfectly cover these topics, showing how molecules and nanostructures can be used to understand how life works, while contributions by young researchers will stimulate fresh perspectives and encourage collaborations. |

Abstract |
The aim of this workshop is to gather the Italian community exploiting and developing nanomaterials and quantum technologies to address key questions in biological and biomedical fields, focusing not only on material characterization, engineering, and technological developments but also on the biological problems addressed by such technologies. Biological and biomedical sciences have always been supported by technological advances, such as tools with better sensitivity and resolution or novel materials with improved properties. One notable example is nanotechnologies in biology, where nanoscale materials and devices are nowadays employed in genomics, imaging tools, drug delivery systems, micro- and nano-sensors, etc. Frontier research now aims to use nanotechnologies to simultaneously excite and probe biological matter. In recent years, quantum technologies have opened new paths for progress. Quantum sensing, that is sensing enhanced by quantum effects, enables the detection of signals that are too weak to be measured with traditional techniques, with potentially revolutionary impacts on biological and biomedical applications. Techniques like nuclear magnetic resonance and imaging (NMR, MRI), likely the best-known examples of quantum technologies applied to biology, can now be performed at the scale of single proteins and cells. Other methods include super-resolution microscopy, sensors (e.g., for temperature, magnetic fields) based on solid-state spins, superconducting quantum interference devices (SQUIDs), and optically pumped magnetometers (OPMs) using atomic ensembles. Applications span magnetic imaging of cardiac cell cultures, nano-thermometry in neuronal networks, and early disease diagnosis via MRI. Bringing together experts with complementary backgrounds, including materials science, engineering, physics, chemistry, and biology is essential for advancing the use of nanomaterials and quantum technologies in biological studies. |

Abstract |
The worldwide rising incidence of diseases, such as cancer, draws attention on the urgent need for innovative strategies in early detection and monitoring. Traditional diagnostic methods often fail to identify diseases at their earliest stages and lack the precision required to guide timely and effective interventions. This session aims to explore innovative multi-analytical strategies that integrate advanced biophysical techniques with statistical and computational methods to address these challenges. This combined approach provides unparalleled and unprecedented capabilities to quantitatively characterize diagnostic targets across molecular, cellular, and tissue levels, delivering a comprehensive overview of their biochemical, morphological, structural, and biomechanical properties. Vibrational spectroscopies, such as Raman and mid-infrared spectroscopy, offer detailed molecular insights into biochemical changes during disease progression [1,2], while advanced imaging techniques, including atomic force microscopy (AFM), confocal fluorescence microscopy (CFM), and X-ray phase contrast tomography (XPCT), add structural, morphological and mechanical characterization, and allows a 3D imaging of the investigated samples [3,4]. When these biophysical information are combined with clinical and molecular datasets and analyzed through multivariate statistics and machine learning, these methodologies can define novel quantitative biomarkers, improving diagnostic accuracy and overcoming the limitations of current tools [5,6]. This event will bring together researchers from diverse fields—physics, engineering, biomedical sciences, and medicine—to discuss cutting-edge approaches that leverage spectroscopy, microscopy, and machine learning for disease characterization. By fostering interdisciplinary collaboration, it will contribute to advancing precision diagnostics and improving patient outcomes. |

Abstract |
Chirality, i.e. the lack of mirror symmetry, appears ubiquitously in nature across a wide length scale, from atomic arrangements in chiral molecules to macroscale objects. Fascinating properties have been associated with chiral interfaces, as layers of chiral molecules onto inorganic nanostructured surfaces. If the transfer of chirality among molecular ensembles is well assessed through the “sergeant and soldiers” principle, it has been demonstrated that a chiral environment can also modify the electronic and optical behavior of low dimensional or nanosized inorganic structures, such as quantum dots or plasmonic nanoparticles, opening interesting possibilities for material engineering as well as sensing applications [1]. The spin dependent electron transport across chiral structures, known as chiral induced spin selectivity, can foster a spin polarized charge transfer, holding great promise for spintronics and novel quantum technologies [2]. Overall, material science and nanotechnology can profit from exploiting structural chirality and the related phenomena to confer novel electronic and optical properties to nanostructures and interfaces [3]. The goal of this Mini-Colloquium is to discuss the physical and physico-chemical phenomena taking place at chiral bio-, nano- and low dimensional interfaces, showcasing some relevant advancements in the field and the novel experimental methods to uncover them, which include (but are not limited to) advanced spectroscopy studies. |

Abstract |
The behavior and function of living organisms are governed by a complex interplay of interactions occurring at nano- and mesoscopic scales. These interactions define the identity of specific functional structures, ranging from biomolecular coacervates within cells to biological interfaces that regulate cellular activity, and extracellular vesicles that play a pivotal role in intercellular communication. The intricate network of physico-chemical and mechanical interactions at these scales underpins the functioning of living systems, from individual cells to tissue organization and beyond, influencing both health and disease. Advancing our understanding of these nano- and mesoscopic interactions requires experimental investigations and the development of complex, biomimetic models. Such efforts are crucial not only for expanding fundamental knowledge but also for enabling clinical applications, particularly in fields like cancer research. Addressing current challenges demands innovative approaches and techniques, including advanced scattering and biomechanical analysis, (label-free) super-resolution and scanning probe microscopy, microfluidics technologies, Bayesian optimization, and machine learning tools. |

Abstract |
Nuclear medicine is currently a field of increasing importance in the fight against cancer. The possibility to rely on a wide number of radionuclides with therapeutic or diagnostic radiation is very attractive for personalized-medicine approaches. In this context, Isotope Separation On-Line (ISOL) is a cutting-edge technique for the production of radionuclides with applications in medicine, biology, industry and more. The strength of this method is associated with the high purity and specific activity of the radioactive beams obtained, thanks to selective processes such as element-specific ionization and mass separation. Crucial steps in the production route, such as the development of optimized targets, the study of photo-ionization schemes for resonant lasers and the manufacture of implantation foils, require expertise in the fields of material science, atomic physics and optics. To understand the effect of these radionuclides on the living cells, the study of radiopharmaceuticals loaded with such agents is important. This radiobiological study often involves 3D tissue-mimicking scaffolds based on biophysics, bioengineering and material science principles. The present workshop aims to provide an overview on such topics and favor the exchange of ideas among the international ISOL community and, in particular, between researchers from the ISOL facilities included in the European network for medical radionuclides, PRISMAP, like MEDICIS-ISOLDE at CERN and SPES-ISOLPHARM at INFN-LNL. |

Abstract |
Using advanced techniques such as focused ion beam (FIB) [1], ion channeling, electron beam irradiation [2], ion implantation, slow highly charged, and swift heavy ion irradiations [3], presents significant challenges in modifying the structural, electronic, mechanical [4], magnetic [5], thermal, and optical [3] properties of materials. The interplay of specific ion-surface combinations, energy regimes, and processing conditions leads to defect formation, material sputtering, and surface morphology alterations. The material's response to individual ion impacts results in various surface nanostructures, including craters, hillocks, caldera-like structures, pores [6] and cylindrical tracks formed inside the bulk [7, 8]. The aforementioned state-of-the-art techniques are crucial for the development of next-generation electronic, optoelectronic, and spintronic devices. In particular, ion-induced defect formation in low-dimensional materials is essential for creating ultrathin membranes for ion beam analysis and nanoporous membranes used in advanced nanofiltration applications [1]. The processes driving these surface modifications are not yet fully understood. This workshop will delve into this topic by combining advanced experimental techniques with cutting-edge theoretical models and computational simulations to uncover the underlying mechanisms. The program will focus on diverse target materials including metals, insulators, free-standing and supported 2D materials, as well as atomically thin transition metal dichalcogenides. Theoretical models, such as the thermal spike model and cohesive energy model (CEM), along with simulation techniques like molecular dynamics (MD), kinetic Monte Carlo (kMC), and density functional theory (DFT), will also be discussed to enhance our understanding of how applied ion beam techniques affect materials' structural, electronic, mechanical, magnetic, thermal, and optical properties. |

Abstract |
The detection and discrimination ionizing radiations and particles, i.e. x- and γ-rays, charged particles and neutrons, are important scientific topics with broad implications for particle physics, astrophysics, radiography, biochemical analysis, medical devices, security technologies and environmental control for radioactive materials. A large part of detectors exploits scintillation counters that record the light pulses produced by the interaction of radiation with a luminescent material, i.e., the scintillator. Despite the technical acceptance of this modality, there is still a wide gap between the current ability of radiation detection and manipulation, in terms of time response, scintillation yield and effective interaction with the biological environment, and the end user’s needs. State-of-the-art materials employed in scintillation-based technologies are not able to satisfy the increasingly performance-demanding application requirements and are poorly versatile. [1] This workshop highlights the recent efforts in material science, manufacturing technologies, and modeling of the physical processes involved in the radiation/matter interaction modelling required to overcame the limitations of actual scintillating materials. [2] [3] In parallel, the most advanced and innovative application of scintillation materials and nanotechnologies in many fields, including environmental control, metrology, diagnostic imaging and radiotherapy.

Abstract |
For decades, transmission electron microscopy (TEM) has centered on achieving ever-higher spatial resolution, with research primarily focused on developing atomic-scale probes and aberration-free imaging. Recently, however, the field has undergone a significant transformation. Emerging trends such as advanced electron-beam control, innovative image reconstruction techniques, and real-time sample manipulation have redefined the scope of TEM. These breakthroughs have elevated TEM from a purely observational and supportive tool to a dynamic platform capable of probing new degrees of freedom within materials - dimensions that were previously inaccessible. Moreover, TEM now enables comprehensive experiments to track and analyze material evolution in real time. This workshop will delve into the latest advancements in TEM as applied to materials science, including cutting-edge instrumentation, AI-driven methodologies, tomography, operando and correlative microscopy, as well as ultrafast, time-resolved microscopy. The workshop will be divided into three sessions focusing on the following topics: - 4D STEM and novel AI-based methods. - In-situ, operando, and time-resolved microscopies. - Pushing the limits of resolution and sensitivity. |

Abstract |
The microscopic electronic interactions dictate the macroscopic behaviour of condensed matter, influencing its structural, electrical, chemical, and magnetic properties. Investigating the electronic structure of materials is therefore essential but often challenging, particularly for systems with significant technological potential. Examples include complex transition metal and rare earth oxides and hydrides, frequently studied in the form of thin film heterostructures or nanostructures, and possibly in operando conditions, such as reactive gas environments, applied biases, or integrated in devices. Advanced spectroscopic techniques that use electrons and photons—such as (hard) X-ray absorption/emission spectroscopy (XAS/XES), X-ray Raman scattering (XRS) and hard X-ray photoelectron spectroscopy (HAXPES)—have proven highly effective for probing the bulk electronic structure of solids. This workshop aims to unite researchers utilizing these methods, showcasing recent developments and insights into materials relevant for technological applications, including oxide-based electronics and hydrogen-based technologies. It also seeks to foster open discussions and strengthen or launch scientific collaborations among the participants. |

Abstract |
The ELECTROSTATIC CONTROL OF MICRO- AND NANO-SCALE ELECTRONIC DEVICES by exploiting the field effect is ubiquitous in nanoscience and technology and traditionally follows the metal-oxide-semiconductor approach. A novel route implying a true paradigm change envisions the use of soft-matter as the gate medium for applying impressively high static electric fields to semiconductors or other materials. This method exploits the way of iontronics to electrostatic gating, using the movement and spatial organization of ions to build up an electric double layer that is the ultimate responsible for the gating action. IONTRONICS targets the control of electrical properties and functionality of electronic devices by exploiting ionic motion and arrangement, and represents an interdisciplinary field encompassing electrochemistry, solid-state physics, energy storage, electronics, and biological sciences. A key element driving the functionality of iontronic devices is the electric double layer (EDL) formed at the interface between an (electronically insulating) ionic conductor and an electronic conductor, e.g. an inorganic semiconductor. In this context, the use of IONIC LIQUIDS (ILs, salts in the liquid state at 300 K) for the realization of EDL transistors (EDLTs) was shown to yield very high local electric fields and efficient carrier-density modulation, and was recently applied to nanomaterials including 2D SYSTEMS (graphene, layered TMDs) as well as QUASI-1D SYSTEMS (nanowires, nanotubes). IONTRONICS AIMS AT presenting the most recent results achieved by the interdisciplinary community working on electric double layer transistors. |

Abstract |
Understanding heat and charge transport in solid-state materials is crucial for addressing critical energy and environmental challenges [1-5]. Recent theoretical efforts in lattice thermal transport have unveiled the critical role of interband phonon conductivity [6], providing a tool for precise estimations of thermal conductivity in complex thermal insulators. Still, significant challenges remain to fully understand heat transport mechanisms in amorphous media [7] and in crystals with strong anharmonicity [8], particularly on the verge of structural instabilities. Significant theoretical advancements in transport in liquids have also led to a unified framework for extracting mass, momentum, and heat conduction coefficients from molecular dynamics simulations. However, unlike solids, incorporating nuclear quantum effects into viscosity or thermal conductivity remains challenging due to the absence of a normal mode expansion, which provides a straightforward quantization of the problem. Finally, recent investigations of transport in solid-state electrolytes (SSEs) via molecular dynamics simulations, often accelerated using machine learning force fields, have partially elucidated the intricate interplay between ionic diffusion and heat dissipation [9]. However, a comprehensive picture on the role of anharmonicities, phonon renormalization, and low-energy ion dynamics in the thermal conductivity of SSEs is far from complete. The proposed workshop seeks to bridge the gaps between transport theory in solids, liquids, and SSEs by bringing together researchers with diverse expertise on the subject. Through focused discussions, the aim is to identify common principles and lay the groundwork for collaborative progress toward a complete understanding of transport theory in condensed, electronically insulating matter. |

Abstract |
The scope of this mini-colloquium is to share and to discuss the latest experimental and theoretical achievements on condensed matter platforms that can harbor non-trivial topological states with the ensuing goal of topologically protected states. During the last decades, topological matter has been one of the major challenges in the condensed matter community. Starting from quantum Hall physics and the search for non-Abelian Anyons, recent interest revolved around the physics of low-dimensional superconductor-semiconductor hybrid systems featuring strong spin-orbit coupling. Motivated by the recent achievements and experimental progress, this Mini Colloquium aims at sharing knowledge and discuss possible pathways in the field. Recent experimental reports have demonstrated the fractional statistics of Anyon quasiparticles in quantum Hall devices, a key quantity that remained elusive for many years. This breakthrough relied on novel interferometric setups and collision experiments, paving the way for new directions toward non-Abelian braiding of Anyons. On the other hand, semiconductors with strong spin orbit coupling, in close proximity to a superconductor, have been predicted to host so-called Majorana zero modes, which are expected to harbor non-Abelian statistics, as well. This prediction led to huge experimental and theoretical efforts, including the study of superconducting-quantum Hall hybrids, with still many open questions. Furthermore, recent experimental advance in the realization of synthetic Kitaev chains based on quantum dots coupled via a superconductor open new avenues to realize a topological superconductor platform.

Abstract |
Strongly correlated materials exhibit interactions so intense that they cannot be approximated by treating particles as independent, posing some of the greatest challenges in modern physics. Central open problems include understanding unconventional superconductivity, quantum phase transitions, and topological states of matter. Quantum computers provide a transformative approach to these challenges, enabling direct simulation of quantum systems. Recent advancements include platforms such as superconducting qubits and trapped ions and milestones like quantum supremacy, demonstrating tasks unattainable by classical computers. However, noise remains a major hurdle, with efforts focused on error correction and developing resilient qubits. Despite these obstacles, progress in algorithms and hardware promises to revolutionize simulations in strongly correlated physics, advancing fields like materials science and quantum information. This workshop will showcase cutting-edge research, including invited talks, contributed presentations, and networking sessions, emphasizing quantum simulation's role in advancing our understanding of the quantum world. Specific examples of quantum simulations that we will discuss include: (1) Quantum magnetism: quantum computers can unravel phenomena such as spin liquids and quantum phase transitions in dimensions where classical methods fail. (2) Nonequilibrium phenomena: Systems like time crystals, which break time-translation symmetry, highlight the potential of quantum simulations to explore dynamic quantum behaviors. (3) Topological states of matter: Simulating topological insulators and Majorana fermions paves the way for robust quantum computing platforms. (4) Quantum chemistry: Simulations of strongly correlated molecules enable breakthroughs in drug discovery and materials science. |

Abstract |
Open-shell molecules, particularly conjugated systems with multiple radical centers, have become central to modern technological applications, including gas sensing, quantum mechanics, photonics, spintronics and photovoltaics. However, the intricate design and reactivity of these species, whether isolated or in assemblies, present significant challenges for both synthesis and experimental characterization. This workshop focuses on the recent advances in optical and X-ray spectroscopies, state-of-the-art organic synthesis and theoretical methods to overcome these challenges. By fostering collaboration between the fields of organic molecule design and condensed matter spectroscopy, the workshop aims to deepen our understanding of the electronic structure dynamics of these molecules and their potential applications in cutting-edge technologies. |

Abstract |
Within the realm of moderately-to-strongly correlated electron systems, 3d transition metal compounds, and oxides in particular, have been the focus of research efforts for several decades for their exceptional electronic and magnetic properties, and their potential for technological applications [1]. In the first two decades of the XXI century, the attention of solid-state physicists is partially shifted towards the less understood domain of 4d and 5d transition metal compounds. On one hand, their chemical properties are reminiscent of 3d transition metal compounds and materials with analogous crystalline structures can be synthesised; one the other hand, their physical properties are heavily affected by the larger extension of the electronic orbitals and the larger spin-orbit coupling owing to the use of heavy ions. Indeed, spin-orbit coupling prevents the quenching of the orbital angular momentum and promotes exotic electronic and magnetic phases that defy the conventional paradigm of distinct spin and orbital degrees of freedom with their own energy scales and symmetries. In analogy to f-electron [2], multipolar orders are expected to occur also in heavy d-electron systems [3], but are challenging to detect because conventional probes, like neutron diffraction, are often insensitive to high-rank multipolar moments that may have too small form-factors or generate no magnetic density at all. Hence, an array of alternative spectroscopic techniques like the resonant elastic and inelastic X-ray scattering [4], nuclear magnetic resonance [5] and muon spin rotation [6] has been applied to resolve the nature of unconventional order parameters in spin-orbit materials. The aim of this workshop is to bring together leading experts and younger researches to review the current status in the field, define actual theoretical and experimental challenges and future research directions, as well as encourage mutual collaborations among the participants. |

Abstract |
Quantum materials are one of the most active research fields in condensed matter physics, encompassing the continuously expanding realm from two-dimensional materials to Kagomé systems, altermagnets and superconductors, as well as their combinations in 2D architectures. These materials exhibit exotic electronic and magnetic properties, which stem from emergent phenomena resulting from strong correlation effects and/or reduced dimensionality. The advanced light sources (e.g. synchrotrons, free electron lasers) contribute significantly to the understanding of these systems, thanks to a complementary and versatile set of powerful spectroscopic and microscopic characterisation tools, including momentum-, space-, time- and spin-resolved techniques. The NelQMat workshop will address the current experimental and theoretical challenges in the broad field of quantum materials, promoting discussion and collaboration among a heterogeneous audience of interested scientists. World leading experts will highlight the most recent research achievements and the opportunities that will emerge with the construction of new light sources envisioned in the coming year |

Abstract |
The quest to explore the world at incredibly small scales has been one of the most exciting and transformative challenges of modern science. It was pioneered by Richard Feynman, who in 1959 envisioned the potential of materials and phenomena confined to low dimensions. Today, we are witnessing the realization of Feynman’s vision through the study of low-dimensional materials — systems reduced to one or two dimensions – often at the atomic or molecular scale. These materials exhibit remarkable properties, vastly different from their bulk counterparts, i.e. enhanced reactivity, altered electronic behavior, and modified surface energies, opening innovative possibilities across diverse fields, from electronics to healthcare and energy technologies. This workshop aims to provide a comprehensive exploration of these unique properties, by discussing a variety of low-dimensional material related topics: • Synthesis and Design: fabrication methods and innovative techniques for novel low-dimensional materials. • Electronic, Catalytic, and Optical Properties: impact of reduced dimensions on electronic transport, optical response, and catalytic activity, and their understanding via cutting-edge tools like scanning probe microscopy. • Defects, Doping and Strain: impact of extrinsic factors on material properties. By fostering discussions among leading experts from various subfields of condensed matter physics, this workshop will emphasize the interconnectedness of these research areas, providing a platform for discussing cutting-edge advancements on low-dimensional materials and offering new insights for their real-world applications. We are confident that this workshop will serve as an inspiring and productive environment where both established researchers and emerging talents can exchange ideas, build interdisciplinary collaboration, push the boundaries of knowledge, and spark the next wave of breakthroughs in low-dimensional science. |

Abstract |
Chemical reactions occurring on surfaces have attracted marked interest in the last decade in virtue of the enormous potential towards the achievement of low-dimensional nanostructures that cannot be obtained via traditional wet chemistry approaches. A blossom of 0D, 1D, and 2D nanoarchitectures with peculiar structural, chemical, and electronic properties, opened new prospects in organic electronics, catalysis, molecular magnetism and nanomotors and boosted fundamental studies exploiting the whole characterization toolkit of surface science. This Mini-colloquium aims to collect contributions on the most recent advancements in the field of on-surface chemical reactions and on-surface synthesis of novel nanomaterials based on covalent bonding as well as coordination interactions. It will focus on: the study of intra- as well as intermolecular reactions on atomically flat surfaces; the design and solution synthesis of custom-made functional molecular precursors; atomistic simulations elucidating the principles that govern the formation and functionality of low-dimensional carbon nanomaterials; atomic scale visualization and investigation of reaction intermediates and products by advanced scanning probe techniques. |

Abstract |
The two-dimensional (2D) materials family, including the Xenes, MXenes, transition metal dichalcogenides sub-families, has provided a new way to explore table-top physics showing a rich scenario of phenomena revolutionizing condensed matter physics. Surprisingly, the wave of interest is not limited to the study of single 2D materials alone. Indeed, recently, additional interesting phenomena showed up when different 2D materials are combined together in a heterostructure. In fact, even when just two sheets of the same 2D material are coupled together, e.g. magic-angled twisted graphene, a lot of new physics can emerge. The additional degree of freedom resulting from the twisting angle between the two 2D crystals turned out to be of paramount importance defining peculiar moiré patterns and determining many electronic and optical properties thus giving rise to a new field of research called twistronics or twisted matter. In this framework, the study of the growth and advanced characterization of 2D materials-based heterostructures paves the way to novel and intriguing opportunities in many fields of nanotechnology. For instance, many applications of 2D material heterostructures in the field of neuromorphic computing, energy-efficient transistors, and low-power memory devices can be foreseen. Moreover, their use in the field of energy harvesting, including photovoltaic devices, shows promising outcomes. This workshop aims to bring together scientists from different areas (physics, chemistry, engineering, material science) to discuss the latest developments in the field of 2D material heterostructures with a focus on both the scientific and technological aspects of (but not limited to) synthesis, materials engineering and processing, device integration, and the many applications in nanotechnology involving 2D material-based heterostructures. |

Abstract |
Two-dimensional boron monolayer (borophene) is a promising material for the next generation electronic devices due to its metallic nature. Although the molecular beam epitaxy remains the typical approach for high-quality boron layer synthesis [1] however, this approach yields different borophene polymorphs of nano-metric size, which are undesirable for the device application [2]. Different aspects of the physics and chemistry of borophene and the possible applications are inspected under different guidelines: 1. Synthesis of borophene and borophene heterostructures on metal substrates. 2. Growth detachment and transfer of 2D boron structures and devices fabrication 3. 3D controlled nanoparticles and nanoclusters on borophene surface 4. Dirac states, superconductivity and topological properties. 5. Hydrogen storage and gas sensing. |

Abstract |
This Focus Session aims at bringing together all the researchers active in the physics of low-dimensional materials assembly that work at the edge between physics, chemistry, and material science. When scaling down materials to the nanometric world, they acquire novel fascinating properties, from which quantum effects stem out and promise to revolutionize several fields, such as optoelectronics, sensing, computing, bioimaging and diagnostics, and so on. Functionalization serves a double role: It safeguards the properties of low-dimensional systems from environmental effects while customizing them for targeted applications. A strong connection between experimental and theoretical physics ensures to comprehend and master the underlying physical mechanisms, while chemistry is required to synthesize and attach the functional groups to the systems, and engineering ability is required to embed them into devices. This mini-colloquium aspires at establishing a convergent platform between synthesis, microscopy, spectroscopy, electronics, and engineering of low-dimensional systems that are functionalized with molecules or nanoparticles to achieve novel magnetic, optical, and electronic properties and their possible implementation into devices in theory as well as in experiment. The colloquium will span material preparation and structural characterization, theoretical modeling, structure-property-function relationships and device fabrication. The ultimate goal is to maintain high the attention towards the fascinating world of layered nanomaterials. With this colloquium, we also aim at bringing together different protagonists of the current research scenario devoted to the better understanding and exploitation of the properties of bidimensional materials, in order to identify common grounds and to exchange valuable ideas for the further development of the field. |

Abstract |
2D materials provide an exceptionally versatile platform for creating a broader range of heterostructures than traditional growth methods, as virtually any 2D material can be combined with another through van der Waals forces. Over the past decade, these heterostructures have revealed a wealth of unique physical phenomena, including unconventional superconductivity, novel excitonic states, or spontaneous photovoltaic effects. The extended range of functionalities offered by such heterostructures has stimulated potential applications across diverse fields, ranging from field-effect tunneling transistors to optoelectronic devices. Fully exploiting their potential and optimizing device performance requires a deep understanding of the electronic and optical behavior of 2D heterostructures. In these systems, interlayer interactions, reduced dimensionality, and broken symmetry concur to produce novel physical properties.
In some cases, these effects can be understood by examining how the electronic structure or optical response of each layer is affected by the neighboring ones. In others, the behavior of the heterostructure as a whole necessitates a non-perturbative approach for a complete understanding. Reduced screening and quantum confinement give also rise to pronounced excitonic effects. This symposium aims to bring together theoretical and experimental experts working in the field of 2D material heterostructures to exchange recent advancements in understanding the original physics of these systems. Topics include theoretical modeling, first-principle simulations and advanced spectroscopic techniques for probing the electronic structure and light-matter interactions in 2D heterostructures. |

Abstract |
Molecular spintronics [1,2] is a field of research that has evolved over the past two decades to exploit the unique capabilities of molecules in spintronic devices. While early efforts concentrated on investigating spin transport through molecular films integrated into spin valves, recent advancements have shifted toward the development of hybrid organic-inorganic interfaces that exhibit novel spin effects beyond the reach of conventional materials. The goal is to find innovative two-dimensional (2D) material platforms with unprecedented functionalities. In this context, numerous examples of hybrid interfaces have emerged, where molecules are coupled with ferromagnetic [3,4] and antiferromagnetic materials [5], as well as 2D magnets [6,7], leading to novel magnetic properties. These include, on one side, the generation of spin-polarized states within organic layers, and one other side, the ability to modulate the static and dynamic magnetic properties of inorganic counterparts [8,9]. The versatility of molecules in responding to optical, electrical, and chemical stimuli presents an unprecedented opportunity to expand the functional landscape of spintronic devices. This workshop aims to unite researchers dedicated to advancing hybrid interfaces, focusing on the creation and exploration of novel low-dimensional magnetic systems with the potential to incorporate multifunctionality. |

Abstract |
This thematic workshop invites contributions exploring the nascent field of altermagnetism. Altermagnets are a recently discovered class of unconventional magnets with no net magnetization but nonzero spin splitting of nonrelativistic origin [1-3]. This unusual combination of features gives rise to phenomena typically associated with ferromagnets, such as the anomalous Hall effect, alongside properties characteristic of antiferromagnets [4-5]. Recent experimental breakthroughs have confirmed the existence of altermagnetism in materials like MnTe and CrSb [6-8], sparking intense interest in understanding the underlying mechanisms and exploring the diverse family of altermagnetic materials. This symposium aims to bring together researchers to discuss the latest theoretical and experimental advances in altermagnetism, fostering collaboration and driving progress in this exciting new field. Topics of interest include: - Theoretical foundations of altermagnetism: symmetry considerations, microscopic models, and electronic structure calculations. - Material realizations of altermagnetism: identification and characterization of new altermagnetic compounds, including bulk materials, thin films, and heterostructures. - Experimental probes of altermagnetism: spectroscopic and transport measurements, and magneto-optical techniques. - Spintronics and device applications: exploration of altermagnetism for spin-current generation, manipulation, and detection, with potential applications in memory, logic, and sensing devices. - Open questions and future directions: unresolved theoretical challenges, promising avenues for experimental investigation, and potential technological impact. This workshop aims to provide a platform for researchers to present their latest findings, exchange ideas, and shape the future of altermagnetism research. We encourage contributions from both theoretical and experimental perspectives, spanning diverse material systems and experimental techniques. |

Abstract |
Molecular spins are largely investigated as prototypical platforms for quantum technologies and spintronics. Indeed, they provide numerous low-energy states that can be harnessed for storing and processing quantum information. This makes them ideal candidates for use both as qubits and qudits (1). This latter encoding enables to expand the power of quantum logic beyond the traditional qubit-based architectures (2) and especially allows to embed QEC in single units. Another major advantage of molecular systems lies in the exceptional control achieved in designing molecules and complex supramolecular structures from the crystal to the adsorbed phase: their grafting and organization on surfaces can allow both the addressability of the spin states at the level of the single molecular unit and their scalability into extended 2D platforms (3,4). Finally, the incorporation of molecule-based materials into spintronic heterostructures, including spin valves and magnetic tunnel junctions, along with the development of fully molecular devices, is generating significant interest (5). This research field therefore combines the efforts of physicists and chemists. They will be gathered at this workshop to discuss recent developments in the design and implementation of spin-based technologies from both theoretical and experimental points of view. |

They enable highly efficient energy conversion and storage, reducing reliance on fossil fuels and contributing to carbon neutrality. Most high-performance PMs rely on rare earth elements (REEs), which are considered critical materials due to their limited supply, geopolitical concentration, and high extraction costs. Hence, ensuring a stable supply is a significant challenge; particularly at the EU, currently importing >90% of the total REE-magnets. On one hand, it is necessary to strengthen the supply chains in Europe, by opening mines and processing plants, and by ensuring secondary material (recycled) as a reliable source. Achieving the latter requires working on the economic feasibility of recycling REE-magnets.[1] A third action that could help reduce supply chain strain is the development of new REE-free magnetic phases that can partially replace REE magnets in some applications, filling the property gap between inexpensive but low-performance ferrites and expensive high-performance REE magnets.[2][3] Great research efforts are currently dedicated to the theoretical calculations, synthesis, processing, characterization and performance optimization of REE-free permanent phases such as α-MnBi and other Mn-based materials,[4][5] AlNiCos,[6] W-type ferrite,[7] α’’-Fe16N2,[8] tetrataenite and other L10 alloys,[9] high-entropy alloys (HEAs), hard-soft composite magnets, etc. This workshop aims to be a forum for discussion and knowledge exchange on the latest advances in the research topic of permanent magnets, covering from the development of well-known REE magnets to the design of novel REE-free materials with the potential to enable a partial substitution. These discussions will span both experimental approaches and multi-level simulation perspectives. |

Abstract |
Spintronics is envisioned as an important game changer for future low power computing technologies and electronics [1,2]. Exploiting the spin and the charge of the electron, it has already revolutionized the magnetic field sensor sector, leading to incredibly high data storage densities in magnetic recording, and tackling the required extreme sensitivities in future biomedical sensors, like brain signal detection. But spintronics has much more profound potentials, such as integrating logic and memory in CMOS compatible devices (for overcoming the von Neumann bottleneck), or realizing hardware for novel computing concepts, such as neuromorphic or probabilistic computing [3]. A large part of research on spintronic devices is dedicated to controlling and fine tuning their properties in order to reach an optimized performance and energy efficiency [4]. The optimization requires three fundamental steps: theoretical analysis of the device performance, careful device fabrication and accurate and reproducible measurements and testing. The measurements of spintronic key parameters such as spin orbit torque efficiency, Dzyaloshinskii Moriya interaction, spin Hall angle, etc., currently show a lack of reproducibility. Different measurement methods show disagreement, even on nominally the same device, limiting the possibility to gain physical insight from the measurement [5]. For fine tuning spintronic properties it is indispensable to combine the measurement with a theoretical model or simulations (e.g. micromagnetics) reflecting the measurement conditions as accurately as possible. Furthermore, novel techniques, such as machine learning, can help to speed up data analysis and make predictions in the absence of a complete model [6]. We call here for papers on the determination and control of the spintronic key parameters with special focus on innovative, high accuracy, reproducible measurement techniques, supported by advanced theoretical and numerical modeling. |

Abstract |
Superconducting circuits are among the most promising platforms for quantum technologies, quantum simulations, and future quantum computing [1]. Remarkable achievements have been obtained in recent years through multi-qubit superconducting platforms, such as quantum advantage at Google [2], and the IBM quantum hardware remote service based on APIs [3]. A key challenge in the development of advanced, scalable quantum architectures is achieving very long coherence times, which drives research into diverse directions. One possibility, that is particularly intriguing both for fundamental and applied science, is to increase the system’s complexity by various means through encoding the information in many-body or highly non-local states. Cutting-edge examples are the parity-protected superconducting qubits [4], the Schroedinger-cat qubit and bosonic qubits [5], and the Andreev qubits [6]. At the same time, the realization of complex circuits integrating novel materials opens exciting avenues to deepen our understanding of superconductivity, quantum networks, quantum phase transitions, and topological phases of matter. The workshop will be designed to have a strongly interdisciplinary character and to foster cross-fertilization among diverse research areas. It will begin with an introductory talk aimed at the entire condensed matter physics community followed by invited talks highlighting the most recent significant advances in the field, and shorter contributed talks focusing on emerging research and innovative developments. At a more technical level, the present workshop will draw connections between different strategies of protected qubit encoding, including dissipation engineering [7], circuit and network optimization, integration of complex materials [8], and hybrid platforms [9]. |

Abstract |
This mini-colloquium aims at providing an overview of superconducting quantum technologies with special emphasis on design and implementation of hardware and quantum control. The superconducting platform provides one of the forefront runners in the race for quantum computing, the main challenge being upscaling the architectures. While optimized single-qubits have already met decoherence figures exceeding the error correction treshold much less is known for composite systems. Problems with upscaling come for instance from spatially correlated decoherence, complexity of control, crosstalk and reliability of the components. To this end new device design solutions, materials and architectures are being exploited. Superconducting hardware is emerging as an important platform for a variety of quantum tasks other than information processing, from components for readout, coupling, power supply and cooling to devices for sensing and components for communication. For all these tasks to be accomplished novel tools for characterize and control quantum complex systems have to be developed. In this scenario topics to be covered in the mini-colloquium are : - novel design of quantum processors in superconducting and hybrid material platforms - quantum control of nonlinear dynamics of superconducting devices - quantum components for readout and coupling - multiqubit and modular superconducting quantum architectures - microwave photon sources, detectors and other components for quantum communication. - quantum decoherence and noise characterization, sensing and mitigation - quantum magnetic sensing, imaging and precision measurements in fundamental physics. - superconducting hardware for quantum energetics |

Abstract |
Modern theoretical and experimental approaches converge towards the possibility to disentangle the effects of spin and charge fluctuations in quantum materials. The most studied materials in this respect are arguably the high-temperature superconductors, where the electron dynamics is crucially affected in a momentum-dependent manner. The kinetic energy decrease associated to the spin dressing can favour the emergence of long-range order, such as charge density waves and high-temperature superconductivity. Here we gather theorists and experimentalists developing novel approaches to disentangle the charge and spin dynamics and unveil the key mechanisms responsible for unconventional electronic phase transitions in materials ranging from copper oxides to kagome metals. The goal is to set the most urgent questions that should be addressed to advance the comprehension of these phenomena. |

Abstract |
The coupling between magnetic and superconducting states offers intriguing opportunities for emerging quantum information tecnologies.1 For example, the interaction between spins from isolated magnetic adatoms or molecules with a superconductor (SC) can generate magnetic states with energy falling below the superconducting gap known as Yu−Shiba−Rusinov states.2 These states also exhibit tunable properties offering interesting playground to control the coupling between spins and a SC surface.3 Highly-correlated magnetic systems like magnetic atomic chains on SCs have also been explored for the realization of Majorana bound states.4 These states are currently studied for the development of topological quantum computing platforms. Molecular magnets can also be exploited to probe magnetic stray fields in a SC5,6 or to modify its screening properties. For example, the adsorption of a layer of chiral molecules on a SC can induce an unconventional Meissner response, which can be in turn exploited for the realization of novel cryogenic devices.7 Like for hybrids of magnetic molecules and SCs, heterostructures consisting of ferromagnet (F) thin films coupled to Ss also host intriguing physical phenomena for spintronics devices operating in the superconducting state with low-energy dissipation. Under appropriate engineering of the F magnetic spin texture, for example, SC/F hybrids support transport of spin-polarized quasiparticles with enhanced lifetimes8 or generation of spin-polarized (triplet) Cooper pairs.9 This workshop reviews advances in the above-listed research topics and aims at stimulating discussion within the scientific community on the rich physics of spins/superconductor interfaces from both an experimental and a theoretical perspective. It aims at emphasizing the diverse processes that can occur at these interfaces, with the idea to brainstorm on future research directions and to identify the most promising approaches to pursue for technological applications. |

Abstract |
The workshop aims at sharing the latest information and ideas on the fundamental properties of surface confined organic semiconductors, self-assembled monolayers (SAMs) and hetero-organic interfaces. It will join the expertise of physical and chemical investigations with different routes to the preparation, synthesis, modification and theoretical modeling of the molecular adsorbates, monolayer films and complex two-dimensional heteromolecular architectures, such as MOFs. The almost unlimited functionalization range of aromatic, heteroaromatic and metal-organic compounds such as, porphyrins, phthalocyanines, fullerenes or PAHs, allows to finely tailor the electronic properties of organic/inorganic interfaces, such as transport, magnetism, photosensitivity and reactivity for the most diverse applications. In this vast field, X-ray spectroscopy provides an atomistic characterization of the influence of the substrate on the electronic and structural properties of the organic adsorbates. Such spatially averaged measurements are essential for complementing the input from local probes for a theoretical modeling of interfaces with effective predictive capabilities. Key topics will include: (i) photoemission and absorption studies addressing a wide range of interfacial properties and phenomenologies, such as molecular orientation and conformation, charge transfer (static and dynamic), magnetism, reactivity; (ii) first principle simulation of spectroscopic results, together with multiscale modeling, to streamline the design of hybrid interfaces with desired functionalities, starting from the elementary building blocks; (iii) recent instrumentation advances, further extending the reach of X-ray Spectroscopy to cover a steadily increasing range of multiple parameter domains: from the bottom of the temporal and spatial scales (sub-fs and sub-µm, respectively), to the top of the temperature and pressure scales (»1000 K and »101 mbar). |

Abstract |
Catalysis lies at the heart of numerous chemical processes vital to industry, energy, and environmental sustainability. However, unlocking the full potential of catalytic materials requires a detailed understanding of their dynamic behavior under operating conditions and the description at different lengths of complex systems such as the solid/gas and solid/liquid interface. This mini-colloquium focuses on operando characterization techniques, which combine structural, electronic, and chemical analysis during catalytic reactions spanning photo- thermal- and electro- catalysis The scope of this session extends across a range of condensed matter topics, exploring how advanced experimental approaches—such as synchrotron-based X-ray methods, electron and scanning probe microscopies, and vibrational/optical spectroscopies—reveal critical insights into the structure-performance relationships of functional materials. Interdisciplinary by nature, this colloquium welcomes contributions spanning materials science, surface chemistry, and energy research, fostering a collaborative dialogue on the latest advancements. By addressing key challenges and opportunities in operando studies, this session aims to bridge the gap between fundamental understanding and practical application, paving the way for the design of next-generation materials with tailored properties. |

Abstract |
Lattice models are now more than a century old but continue to represent one of the favorite subjects of statistical physics, to which they have made fundamental contributions. This applies both to the development of new theories and to numerical simulations, giving rise to a synergy rich in implications. New, very powerful tools such as artificial intelligence and machine learning have recently appeared on the scene which, together with the availability of powerful computational resources, promise to revolutionize our way of understanding scientific research. This also applies to lattice systems and this workshop is an opportunity to talk about it. |

Novel views on statistical physics of polymer conformations and dynamics: phase segregation and topology |

Abstract |
Polymers are amongst the hugest molecules in the Universe. Essentially, they are made of single, small, units that covalently bond to each other into large aggregates. For their properties, they have a significative impact in everyday’s life [1]. Back in the 40-60’s of the XX century, pioneering work by notable people such as Flory, Zimm and Stockmayer [2-4] showed that the problem of the characterization of polymer conformations can be expressed by using the language of statistical physics. Later on, in the late 60’s until the end of the 80’s [5-7], polymer physics was at the center of active investigation. In particular the field was shown to be closely connected to the theory of critical phenomena, a remarkable achievement that constituted a new starting point in the field. Coming to more recent years, research in polymer physics focuses, amongst others, on two main subjects, namely the role of topology [8] in shaping polymer structure and dynamics (with particular reference to entangled solutions of non-concatenated and unknotted ring polymers [9,10]) and the quantitative description of phase separation mechanisms in polymer/solvent mixtures [11,12] (that is believed to play as a main actor in DNA organization in the cells [13]). Together, these fields will occupy researchers for years to come. The aim of this MiniColloquium is to provide a state-of-the-art present understanding of where we stand as well as the future directions in this field, by gathering together different experts in modern polymer physics and foster a scientific discussion as well as collaboration between the participants in the event. The structure of the MiniColloquium is then envisaged as follows. After a first introductory statement by the Chair, partially invited and partially selected contributions from the participants will be scheduled, and a final round table discussion will take place that will pave the way towards future investigations. |

Abstract |
This mini colloquium focuses on the latest advances in quantum thermodynamics[1,2] and thermoelectricity[3,4], bringing together leading experts in the field. One of the most fascinating challenges for sustainable quantum technologies is to develop efficient miniaturized thermo-electronic devices that maximize the heat conversion into electricity, while minimizing heat waste within a finite operation time[5]. On the one hand, classical bounds to the efficiency of thermal machines are not quite informative, as they apply to infinitely slow operations[6,7]. On the other hand, the effects of quantum correlations, which have been studied for many years in computing, communication, and solid-state systems sensing methods, are still far from being fully understood when it comes to thermodynamics at the nanoscale. Quantum thermodynamics and thermoelectricity investigate the impact of quantum phenomena on the efficiency of nanosystems and devices and their possible applications[8]. This minicolloquium offers an opportunity to discuss results crucial for the broad field of quantum technologies where heat management and heat harvesting are essential to solve the scalability issues of the quantum circuits as required by the more recent roadmaps to build a profitable quantum computing platform[9]. |

Abstract |
The interplay between disorder and correlation is a central challenge in condensed matter physics, particularly in low-dimensional systems where both effects are inherently non-perturbative. At low temperatures, the competition between these factors becomes crucial. Strongly correlated low-dimensional systems display a range of unique behaviours: some arise from enhanced disorder, while others preserve the characteristics of their cleaner analogs. Understanding the development of different ground states and their response to external excitations remains a significant theoretical and experimental challenge. One prominent example is the ongoing debate over the evolution of the superconducting order parameter in strongly disordered superconductors. Additionally, the interaction between disorder, correlations, and nontrivial topology holds considerable theoretical and technological relevance. This mini-colloquium brings together leading experts to address emerging topics in this field, spurred by advances in experimental techniques, the development of novel materials, and new theoretical insights into the physics of strongly correlated and low-dimensional systems. |

Abstract |
Quantum energetics deals with the study of energy-conversion schemes in nanoscale systems, where fluctuations and quantum effects play an important role. Technological advances have allowed us to better understand and manipulate heat exchange at the nanoscale [1], opening exciting opportunities to implement quantum analogues of standard thermal machines from classical thermodynamics. Besides relying on traditional mechanisms, such as thermoelectric conversion [2], machines operating at the quantum level can also exploit “unconventional” resources, such as non-equilibrium states, engineered reservoirs, information, quantum coherence, measurements and correlations [3] to achieve thermodynamics tasks, such as work extraction. While in the previous decade such features have been pinpointed as sources of apparent violations of established classical thermodynamics bounds, recently many efforts have been directed to theoretically describe the latter in terms of resource theories, similarly to the case of entanglement and quantum information. At the same time, thanks to the noticeable advances of experimental quantum coherent platforms [4], experiments on quantum thermal devices have ultimately left their state of infancy, becoming increasingly more reliable. Indeed, thermoelectric heat engines [5], as well as quantum absorption refrigerators [6], and information-driven devices like Maxwell’s demons [7, 8], have been experimentally demonstrated in condensed matter or cold-atom platforms. The scope of this mini-colloquium is to share the latest developments in the field of quantum energetics, promoting multi- and interdisciplinary connections between quantum thermodynamics, resource theories, and condensed matter, in a similar spirit as the recently launched quantum energy initiative [9]. We aim to bring together experts from different communities to foster collaborations and set common goals for a more complete characterization of machines exploiting quantum resources. |

Abstract |
A pressing challenge in energy production today is identifying alternatives to fossil fuels, which pose significant issues such as toxic and greenhouse gas emissions, finite availability in the medium term, and supply vulnerabilities due to geopolitical tensions. Transitioning to renewable energy sources is therefore a critical priority in modern research, but it also leads to relevant challenges in both energy production and storage. The quest of advanced new materials for solar energy conversion and efficient energy storage requires a deep understanding of the underlying physical processes. In this context, X-ray Absorption Spectroscopy (XAS), Emission Spectroscopy (XES), Photoemission spectroscopy (XPS) conducted under operando conditions has proven to be an invaluable analytical tool. This workshop aims to gather experts from the scientific community engaged in the development of novel materials for sustainable energy production—such as (photo)electrolyzers, photovoltaics, and fuel cells—and energy storage systems like batteries. The focus will be on characterizations performed under static or operando conditions, alongside time-resolved studies. |

Abstract |
This workshop, organized in collaboration with SILS, is aimed at bringing together the growing scientific community that utilizes FEL and XFEL radiation as a unique tool in the investigation of materials, systems and processes for clean and sustainable energy solutions. Free Electron Laser facilities offer ultra-short and extremely bright photon pulses in an extended energy range, from the UV to the hard X-ray regime, to investigate matter at the timescales of electron and nuclear dynamics with chemical selectivity and bulk sensitivity. As such, they are having an important impact in our capacity to understand charge flow in (photo)chemical reactions, energy conversion in photoactive systems, ultrafast electron and ion motion in batteries, catalytic behaviour on fundamental scales, etc. Ultimately this research will contribute to establish design principles for cost-effective and sustainable chemical transformations, bio-inspired clean energy solutions and the directed design of nano-catalysts with tunable properties. With the success of the FERMI (Trieste), the first seeded FEL worldwide, Italy has gained both international visibility and a leadership position in FEL science. Italy is also a shareholder of the European XFEL (Germany), where it has witnessed in the past few years a significant increase in its scientific use. Today, the Italian scientific community orbiting around (X)FELs may have reached a level of maturity that justifies the creation of an Italian XFEL Hub, on the model of those existing in other European countries (Spain, France, UK for example). This workshop – focused on one of the most important scientific areas optimally addressed by (X)FEL methods - could be an opportunity to start this discussion. |

Abstract |
Plasma physics is a multi-disciplinary research field exploring the dynamics of ionized matter across diverse contexts, ranging from space and relativistic astrophysical plasmas to fusion energy research, non-neutral plasmas and cold plasmas with technological applications. Recently, the great effort that has been pursued is to bridge theory, experiments and numerical simulations developed in the different research areas to study universal plasma processes. Turbulence and magnetic reconnection are among the prominent phenomena responsible for the energy transfer towards smaller scales, leading to the emergence of self-organized structures and collective behaviors that underlie the complexity of plasma dynamics. How the energy contained in large-scale fluctuations cascades all the way down to kinetic scales, and how such turbulence interacts with particles, remain key unsolved problems in plasma physics, with strong implications for space, astrophysical, and laboratory plasmas. A synergistic multi-disciplinary approach is required to investigate the basic processes determining the plasma complex dynamics, from theoretical models [1,2] to in-situ measurements [see, e.g., 3], through laboratory [see, e.g., 4] and numerical experiments [5-7]. Within this workshop, we propose to bring the discussion on the main topics of plasma physics, such as energy conversion/dissipation in collisional and noncollisional plasmas, magnetic reconnection, turbulence, plasma waves and instabilities. A particular emphasis will be laid on (a) energization processes and the interplay of energetic particles with the thermal, background plasma; (b) the complex phase-space dynamics associated with non-equilibrium particle distribution functions, as frequently observed in weakly-collisional plasmas, (c) the adoption of multi-disciplinary methodologies from complex systems to highlight new features of plasma dynamics and (d) the discussion of recent advances in space and laboratory plasmas. |

Abstract |
Advancing our understanding of fundamental processes in condensed matter triggered by light pulses underpins the ability to control materials properties for relevant applications. The achievement of this goal requires accessing ultrafast time scales with elemental and chemical selectivity. Nowadays, modern photon sources, such as free electron lasers (FELs), made it possible to address this challenge. Ambitious R&D and upgrade plans are ongoing at FERMI with FERMI2.0 [1], FLASH with FLASH2020+ [2] and SwissFEL [3]. These are aimed at extending the FEL seeding approach, which is expected to provide higher stability and coherence, into the multi-100s eV spectral range, with the additional benefit of polarization control, that enables the study of magnetization dynamics and chirality. This range permits the study of light atoms of highest chemical and biological interest (C, N, O), as well as of 3d transitions metals (Ti, Fe, Co, Ni, Mn, Cu, etc), which are of critical importance for magnetism and quantum material technology. In addition to absorption and emission spectroscopy, X-ray dichroism, resonant scattering and imaging, the spectral brightness of seeded FELs will facilitate nonlinear X-ray methods, such as second harmonic generation, transient grating and four-wave-mixing. This workshop aims to gather scientists within the broad community of solid state physics and materials science, and experts in photon source development, including laser-driven high harmonic and plasma sources, with two main objectives: (i) showcasing the most recent breakthroughs and (ii) stimulating collaborations in a cross-disciplinary context, encompassing the study of quantum materials, magnetism, nanoscale transport phenomena of electronic, spin and phononic nature, chemical reactions at surfaces, molecules and enantiomers. A total number of 12-15 invited speakers and as many contributed talks are foreseen. We plan to include a poster session and a thematic appetizer. |

Abstract |
Excitons, which are bound states of electrons and holes, serve as a key platform for investigating nonequilibrium processes in solid state systems, ranging from semiconductors to two-dimensional materials. Recent advances in time-resolved spectroscopies are paving the way to access regimes which go beyond the simple perturbative one. Upon strong and/or selective excitation, many-body phenomena, such as excitonic Mott transition, superradiant emission or excitonic condensation, have been recently reported. The goal of this symposium is to bring together experimentalists and theorists that are currently investigating collective and many-body phenomena in exciton gases. Within a joint cross-community meeting, we wish to encourage exchange of ideas and identify emerging questions for future research directions and collaborations. |

Abstract |
The recent years have witnessed an increasing interest in quantum phenomena in complex systems operating at room temperature. A variety of them are topics of intense investigation, ranging from, e.g., chromophores in nanoclusters, to quantum emitters coupled to plasmonic resonators. All of these studies highlight how quantum physics is at work when coherence times are extremely short. The investigated physical phenomena are broad, covering non-adiabatic quantum dynamics and conical intersections in molecules and their aggregates in solution and in solid state thin films, vibronically driven charge transfer processes, coherent energy transport in strongly coupled polariton systems and even spin dynamics in proteins that are thought to be relevant for sensing of magnetic fields by migratory songbirds. This requires an interdisciplinary approach for advancing theoretical methods, in particular time-dependent ab-initio techniques, and experimental techniques, such as multidimensional electronic spectroscopies.

Abstract |
Recent advancements in ultrafast light sources have opened unprecedented opportunities for probing ultrafast dynamics across a broad range of wavelengths, from the micrometer to Angstrom scale. These developments enable innovative experimental techniques and provide access to the properties of materials at the nanoscopic level, which were previously unreachable. Femtosecond sources allow researchers to explore electron diffusion dynamics and the interactions between electrons and quasi-particles such as phonons, magnons, and excitons. Additionally, the tunability of these sources enables resonance with vibrational states crucial for molecular science and life sciences, as well as with core levels, offering deeper insights into phenomena related to chemical selectivity. Furthermore, HHG in condensed matter by ultra-intense femtosecond sources allow for real-time probing of attosecond phenomena such as electron-electron interactions, sub-cycle electron tunneling, and charge migration.This workshop will focus on the latest breakthroughs in ultrafast spectroscopy techniques, including optical laser-based methods, spectroscopy methods based on High Harmonics Generation (HHG) and Free Electron Laser (FEL) sources, and HHG spectroscopy. These technologies have bridged different scientific fields, facilitating interdisciplinary collaborations that span multiple spatial scales. Applications of these techniques range from the investigation of 2D materials and thin films to the study of materials used in solar energy conversion and the development of magnonic and spintronic devices. By bringing together a diverse scientific community, this workshop will present the state-of-the-art in nanomaterial research, utilizing ultrafast experimental methods that cover a wide range of the electromagnetic spectrum. The exchange of expertise and methodologies across disciplines will foster new international collaborations, serving as a foundation for future scientific breakthroughs. |

Abstract |
The ultrafast (femtosecond to nanosecond) response of condensed matter systems—including bulk materials, 2D nanosheets, 3D nano-objects, and biological tissues—reveals the intricate interplay of mechanical processes, such as lattice vibrations and acoustic wave propagation, and thermal processes, including heat diffusion and carrier interactions. Over recent decades, these phenomena have been increasingly studied to understand both classical and emerging physical behaviors, as well as to develop applications in areas such as sound propagation in tailored nanomaterials, non-diffusive thermal transfer regimes, photoacoustics, and thermal optimization of nanocomposites. This workshop aims to bring together experimentalists and theorists to discuss key topics in ultrafast dynamics, including opto-acoustics, ultrafast transient absorption, Brillouin scattering, and time-resolved optical and X-ray pump-probe techniques. Theoretical contributions will cover analytical models, molecular dynamics simulations, and ab-initio methods to study heat and mechanical transients at ultrafast timescales. By balancing experimental and theoretical perspectives, the workshop seeks to provide a comprehensive understanding of these processes and foster interdisciplinary collaboration. |

Abstract |
The latest advances in the generation of intense and ultrashort THz light pulses paved the way for a new area in the investigation and control of many complex materials. A variety of experimental protocols, ranging from third-harmonic generation to THz pump-probe and multidimensional spectroscopies, have made it possible to selectively excite low-frequency collective modes, to study quasiparticles coupling and to explore metastable phases of matter on ultrafast timescales. If used as excitation mechanism, few-cycle THz pulses can resonantly drive coherent lattice vibration, spin fluctuations or electronic excitation in a large variety of materials. For instance, in superconductors, it is now possible to resonantly excite the Higgs mode [1-2], an oscillation in the amplitude of the order parameter. In the strong-field limit, it is feasible to access out-of-equilibrium phases of matter, metastable states, and, ultimately, to use THz light to drive phase transitions. Notable examples include THz-driven control of magnetic order [3], ferroelectricity [4], dynamical multiferroicity [5], and light-induced superconductivity [6]. When two THz pulses are applied simultaneously, as in THz 2D spectroscopy, one can investigate the dynamical interplay between nonlinearly coupled collective excitations [7]. In parallel with the experimental progress, significant theoretical efforts have been directed at understanding the nonlinear light-matter interaction at THz frequencies. These efforts involve extending conventional many-body and ab-initio methods, as well as developing new computational techniques to describe light-driven nonequilibrium dynamics [8-9]. This workshop aims to bring together experts from the ultrafast THz spectroscopy community to discuss the latest theoretical and experimental findings, identify remaining challenges, and propose new research directions, taking advantage of the high visibility and dynamic environment provided by the FisMat conference. |

Abstract |
Friction and lubrication are crucial in nature and technological applications (1), ranging from the motion of ions and metabolites in cells and the function of our joints (2) to electrolytes motion in energy devices (3), industrial machinery, car engines (4), and the tectonic dynamics (5). Despite its ubiquitous relevance in different areas of physical, chemical and biological sciences, a comprehensive picture of friction and lubrication is still lacking (6). This is because most macroscale technological applications are still based on semi-empirical models. Over the last twenty years, intense experimental and computational research based on multiple techniques, from molecular dynamics and atomic force microscopy (6) up to ball-on-disc (7), has however helped to elucidate the fundamental mechanisms behind friction and lubrication, from the role of roughness-driven entropy in lubricants molecules adsorption (6) to the role of frictional anisotropy behind earthquakes (5). Altogether, the field is moving towards a more comprehensive model for friction and lubrication beyond semi-empirical observations. Within this workshop, we will cover friction and lubrication from the perspective of different experimental and computational techniques thus exploring the phenomena at different length and time scales. Invited and contributing speakers will highlight the newest and most exciting findings of their recent studies. |

Abstract |
The interplay between light and matter has long been a topic of great research interest and is at the heart of countless applications, including some of the most recent quantum technologies. In the last decades, great efforts have been dedicated to light-matter systems, with the goal of enhancing coupling between light and matter, designing novel architectures, and engineering desired properties in quantum materials. More recent developments have showed that embedding a quantum system in a cavity modifies thermal dissipations, chemical reaction rates and other dissipative properties, even in the absence of strong coupling. The aim of this workshop is to explore the research frontiers of light-matter systems, bridging fundamental physics with applications across diverse platforms – such as optical cavities, plasmonic nanostructures, and emerging hybrid systems – and investigating various regimes ranging from the Purcell regime to the strong coupling regime. The workshop will cover both theoretical and experimental themes: 1. Investigate collective quantum behaviors in light-matter interactions, including super-radiance, hybrid states and effects in the ultra-strong coupling regime. 2. Explore the impact of cavities and structured photonic environments on dissipative effects and light-matter interactions, with applications in sensing, energy transfer, cooling of atoms and molecules, chemical reactions. 3. Applications to Quantum Technologies and to novel quantum materials via the design and implementation of innovative platforms and architectures to enable tunable coupling strengths between light and matter. |

Chirality in high harmonic generation and photoelectron spectroscopy |

Abstract |
Chirality is the property of an object which cannot be superimposed with its mirror image by any translation or rotation. This minicolloquium will show recent advances in the study of chirality in ultrafast processes occurring in molecular systems and materials, both from a theoretical and experimental point of view. Even if chirality has been the subject of deep investigation, the dynamics of transient chirality during ultrafast processes is still mostly unexplored. Indeed, high-harmonic generation (HHG) and photoelectron (PE) spectroscopic techniques allow one to investigate chirality on the femtosecond timescale. HHG is a highly nonlinear optical process providing coherent XUV and soft X-ray radiation with attosecond duration. HHG is a powerful tool to capture the photoinduced electron dynamics, as recognised by the Nobel Prize in Physics in 2023. Such methodologies have been successfully applied to probe chemical reactions, to investigate chirality in excited electronic states, to follow changes in chirality along photoinduced relaxation in molecules, and to detect circularly polarized harmonics from surfaces. The participation of internationally recognized HHG and PE experts will provide an opportunity to discuss cutting-edge developments and results in the study of ultrafast chirality, which is not accessible by traditional experimental setups. Furthermore, the support of theory, including model development and ab initio simulations, is crucial for a homogeneous advancement of knowledge in this field, and therefore adequate space will be given to theoreticians. |

Abstract |
The entry into force of the Chips Act on Sept. 21th 2023 [1] has marked the beginning of a renewed commitment for Europe to advance its semiconductor capabilities, to enhance its technological sovereignty, to secure its position in the global semiconductor market and to support the digitization of economy. The quest is for digital devices and systems of increased performances, efficient and energy-sustainable. Different materials, physical principles and technologies underlie various functionalities, but one general common trait is the continuous miniaturization of semiconductor devices, the increasing complexity of chips-integrated systems and the need to develop novel solutions of monolithic and-or hybrid 3D integration. Device shrinking to the nanoscale also implies to operate at the quantum regime. Whether it is heterostructures or 2D materials, functionally-active nanostructures or defects, whether it is nanostructuring by top-down processing or by bottom-up self-assembly, whether it is integrated systems obtained with monolithic or hybrid 3D technologies, in quantum-scale devices and systems surfaces and interfaces play a fundamental role. In this frame, to provide spectroscopic analytical techniques with sub-micron and nanoscale probing capabilities is crucial to provide spatial information about the electronic and magnetic structure of materials at surfaces, interfaces and in the presence of structural defects. The workshop will present latest advancements in spatially resolved electron and optical spectroscopies applicable to materials and devices, also including dynamical and ultrafast implementation and supporting quantum theory.

Abstract |
Number and statistics property of the fine structure constant, alpha, are discussed. A quantum-relativistic interpretation of alpha, associated with a black-body of volume V at an equilibrium temperature T, is conjectured. In a one-dimensional geometry we find alpha=A K_B T tau/h, with A a numerical constant, K_B the Boltzmann constant, tau an appropriate photon lifetime and h the Planck constant. The physical implications will be the main subject of open discussion. |

Abstract |
Water is by far the most abundant, versatile, and common solvent, as well as the key component of all living organisms. Water exhibits a fascinating array of unusual properties both in pure form and as a solvent, such as anomalous phase diagram, crystalline polymorphs, high dielectric constant, increasing liquid fluidity with increasing pressure, high-mobility transport for H+ and OH- ions. Although it has been the subject of several experimental and theoretical investigations, many issues concerning solute-induced changes in water structure and their influence in fundamental processes such as aqueous multiscale assembly, folding, and binding of biomacromolecules remain still unclarified. Moreover, even if water is widely used for key technologies and numerous industrial processes, the underlying processes involving this solvent at the molecular level are often poorly understood. Molecular water science aims to investigate these mechanisms – in pure water, in small clusters in the gas phase, in aqueous solutions, at interfaces, or on biomolecules, using both experimental and theoretical techniques. In this workshop, we propose to bring together researchers in the field of molecular water science to build collaborations among leading scientific experts and to combine key competences to create the base knowledge for tomorrow’s sustainable technologies. |

Abstract |
The evolution of electronic devices and computational architecture demands innovative technologies and approaches, as traditional CMOS technology faces significant challenges and bottlenecks. Over the past decade, research into novel computing paradigms—such as neuromorphic computing, in-memory processing, and reservoir computing—has made remarkable progress. These approaches address critical issues, including device scaling, energy efficiency, and data movement, however, numerous challenges remain unresolved. A persistent concern in electronics is heat production and elevated device temperatures, often viewed as detrimental due to their contribution to device degradation and increased energy consumption, which undermines device reliability. Yet, thermal management is a crucial aspect of future technologies, with the potential to transform heat into an advantage instead of a drawback: particularly in oxide materials, significant opportunities exist to modify thermal properties and tailor them to meet specific device requirements. Oxides have been explored as thermoelectric materials, capable of harvesting waste heat and converting it into electricity, as well as thermal switches that enable directional and tunable heat propagation. Beyond these applications, heat has the potential to be used as a computational element [1], as a means of acceleration of filamentary memristive devices [2], or as a key element for future neuromorphic computing applications [3]. This workshop aims to bring together researchers exploring innovative concepts in heat and thermal management for electronics. It will focus on exploring thermal phenomena to overcome current technological bottlenecks, enabling new pathways for low energy, faster, and more reliable device operation. By fostering discussion and collaboration, this workshop seeks to inspire groundbreaking ideas in computational design and pave the way for energy-efficient, thermally optimized electronic architectures. |
