By contrast, the recent remarkable achievement by AlphaFold [3] in the challenging 14th Critical Assessment of protein Structure Prediction (CASP14) that outperformed all alternative approaches in the prediction of the native state given the sequence, has brought in the limelight the power of data-driven approaches hinging on artificial intelligence/machine learning techniques. Not surprisingly, Science has nominated this as a 2021 breakthrough of the year [4]. However, predicting the fold does not mean understanding the folding mechanism, and this has stirred significant discussion within the scientific community, especially of the fact that a definite answer on this point will come only by combining the power of data-driven approaches with well conceived coarse-grained models [5].

The aim of this MiniColloquium is to present the state-of-the-art understanding of where we stand, as well as to indicate the future directions in this field, by gathering together different experts in the two techniques and foster a scientific discussion as well as collaboration between the two communities that eventually will reconcile these two approaches.

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 two different approaches will be scheduled, and a final round table discussion will take place that might pave the way toward this reconciliation.

This research has its origin in a prediction formulated more than 50 years ago by a group of visionary physicists: If a narrow-gap semiconductor failed to screen its intrinsic charge carriers, then excitons---electron-hole pairs bound together by Coulomb attraction---would spontaneously form. This would destabilize the ground state, leading to a reconstructed ‘excitonic insulator’---a condensate of excitons at equilibrium. This chimeric phase shares similarities with the BCS superconductor: a distinctive broken symmetry, and collective modes of purely electronic origin. Its observation was deterred for decades by the trade-off between competing effects in the semiconductor: as the size of the energy gap decreases, favoring spontaneous exciton generation, the screening of the electron-hole interaction increases, suppressing the exciton binding energy.

In the last two years, mounting evidence has been accumulating in 2d materials, as they combine truly long-ranged interactions and giant excitonic effects. New electron-hole bilayers hold promise of room-temperature superfluid behavior [1-4], whereas signatures of the bulk phase were found in monolayers [5-7]. Excitonic materials exhibit other kinds of order as well: a variety that includes topological insulators [6-8], ferroelectrics [8,9], unconventional superconductors [6-7,9]. This introduces new far-reaching questions, concerning the role of excitonic correlations in a plethora of allegedly unrelated phenomena, whose interplay is just beginning to be explored. At the same time, the long-term challenge of establishing the EI through the signatures of macroscopic quantum coherence is attracting renewed interest.

By collecting the key actors of theoretical and experimental research, who are spread among different communities, we aim at in-depth analysis of common themes and novel challenges, to progress our understanding of 2d interacting systems.

An easy method to produce nonlinear waves is through bombardment with alpha or other
particles. Created nonlinear excitations produce the ejection of an atom at the opposite side of a crystal, and hyperconductivity, i.e., and electric current in the absence of an electric field. The possibility of serious negative effects induced by this type of charge transport in tokamak fusion reactors need to be addressed and evaluated.

Spectral theory is an efficient tool for analyzing exact solutions and interpret neutron spectroscopy. Wavelet analysis is useful for detecting transient localization. For nonlinear waves transporting charge the difference in time scales between electrons and atoms brings about the need of developing numerical methods that conserve all the properties of the physical system.

Biological systems are also of particular interest. For example, enzymes catalyze biochemical reactions that are essential to life often through rate-promoting vibrations localized at the active sites that couple to the reaction coordinates, thus increasing the reaction speed by many orders of magnitude.

We need novel theories and mathematical methods to predict properties that can be measured and more experimental proofs of localization. Among relevant topics one may list spectroscopy, interaction with defects and phase transitions, electric currents, carrier density, and production by plasmas and ions. This is the objective of the mini-colloquium.

The scope of this symposium is to combine different platforms, such as cold-atoms, photons in cavities and artificial materials to tackle problems relevant for strongly correlated quantum materials. The invited speakers will contribute to define a broad class of problems, such as coherent transport in periodic and disordered lattices, collective phenomena in proximity of Mott insulating phases and cavity enhanced or topologically-protected long-range coherence, that impact on the current understanding of the macroscopic properties of materials. Particular attention will be dedicated to the definition of common goals that can be achieved by hybrid approaches resulting from the combination of different platforms.

This mini-colloquium aims at being the first international stage where, after three years of continuous and hectic breaking discoveries, a fixed point will be drawn. In a 2.5 hours format, three invited talks from renowned leaders in the field and 4 contributed talks are envisioned. In addition, the mini-colloquium wants to be the perfect platform to discuss still open questions and highlight meaningful perspectives for future investigations. Owing to the richness of the physics of kagome metals and their interdisciplinar character, the mini-colloquium will be of high interest to the broad community of CMD.

While there has been much experimental progress in the field of photon-modified material properties, many of the effects are not well understood and theoretical explanations remain controversial. In order to gain a detailed understanding many new phenomenological models [5,6,7] as well as ab-initio methods [8,9] have been developed in recent years. In this mini-colloquium we want to provide an overview of these developments and the field of photon-modified material properties.

Several lectures by experts will cover the latest theoretical and experimental developments in cavity-modified materials that combine ideas and concepts from condensed matter physics, quantum optics and electronic structure theory to understand how quantum electrodynamics influences condensed matter systems.

This minicolloquium will cover the results of recent experimental and theoretical efforts dedicated to (1) the design and implementation of methods to enhance the coupling between quantum emitters and confined photonic or phononic modes. The enhancement is not limited to an increased coupling strength, but it also consists in considering novel forms of interaction beyond the standard dipolar coupling. We consider both genuine (emerging naturally from the system bare components) and parametric (mediated by external fields) couplings. (2) The exploration of the novel quantum phenomenology induced by such unconventional light-matter interactions, both concerning fundamental aspects and possible applications in quantum technologies. (3) The design and the demonstration of advanced quantum controlled dynamics in ultrastrongly-coupled structures.

ETs have always played a fundamental role in condensed matter physics, from elasticity theory and hydrodynamics to Ginzburg-Landau theory, Fermi liquid theory and the more modern ideas about symmetry-protected topological phases. In addition to that, these approaches have provided a a fertile exchange of ideas between high energy physics and many-body theory with a rapidly growing net of dualities, generalized symmetry principles, commonalities and shared interests between different physics communities.

The aim of this mini-colloquium is to review recent progress in the application of effective theory methods to condensed matter problems. Particular emphasis will be put on the three most interdisciplinary and successful approaches: the Gauge-Gravity duality, hydrodynamics and effective field theory. Novel methods, latest results and most promising avenues of these effective methods for condensed matter will be presented by the top researchers in the fields, creating a synergic and exciting environment for the next future discoveries.

Such advancements have created new possibilities to optically control materials and expose hidden phases in them, and have allowed for understanding the working mechanisms of catalytic materials. In addition, it is now possible to investigate the origin of macroscopically observed behaviors in quantum materials, where nanostructuring and spatial dependence of different phases play a fundamental role. Overall, the latest developments have made photoemission spectroscopy even more crucial for finding efficient ways to prepare and characterize novel materials such as 2D materials, topological insulators, molecular networks, nanoparticles and atomic clusters.

This mini-colloquium is intended to showcase the non-traditional applications of photoemission enabled by the recent instrument and technique advances. We would like to gather experts at the forefront of research with photoemission spectroscopy techniques, interested in expanding their knowledge about novel synthesis methods and the technical developments ongoing in the field that allow the preparation and investigation of particularly challenging materials, devices and out-of-equilibrium systems. Theoretical advances are also of high interest to the community and we encourage theoretical colleagues to attend as well.

The behavior of AMs under a mechanical load is a key property with strong practical implications. Measuring, understanding, and modelling the relationship between the mechanical properties and the evolution of the microscopic structure and dynamics in AMs is a formidable challenge for academic research. Indeed, while their behavior at rest or in the linear regime is well understood, much less is known about the non-linear regime, where permanent damage is induced in the material, eventually leading to failure.

Mechanical loading is a popular way of driving AMs. However, other driving modes, e.g. osmotic stresses, thermal cycling, irradiation, or electric fields will also be covered in this Mini-colloquium, aiming at identifying common features across fields and sub-disciplines that are rarely gathered in a single scientific meeting. CMD30 – FisMat2023 provides a unique opportunity to bring together a diverse community interested in several fields at the core of CMD30: soft condensed matter, biophysics, materials science, structural and mechanical properties of materials, and disordered media.

We will organize sessions comprising one or two 30’ invited talk and several 15’ contributed talk, each session covering a key question or ‘hot’ research topic:
1. The nature of the yielding transition: new approaches in theoretical modelling.
2. Driven biologically systems.
3. Precursors of material failure at the microscopic level: can we predict and anticipate failure?
4. New experimental methods to probe the dynamics and structure of driven AMs.
5. Numerical simulations: towards a multiscale modelling.

This Minicolloquium therefore aims to bring together scientists from different areas (physics, chemistry, engineering, material science) to discuss the latest developments in the field of Xenes with a focus on both the scientific and technological aspects of the synthesis, processing, characterization, modeling, and applications of these 2D materials.

Topics to be covered by the Minicolloquium (but not limited to):

-synthesis of Xenes: epitaxial growth and segregation, chemical vapour deposition, mechanical and chemical exfoliation/deintercalation.

-characterization of Xenes: in- and ex-situ microscopy (STM, AFM, TEM, …) and spectroscopy (X-ray, Raman, and optical).

-theoretical predictions of Xenes: electronic, optical, magnetic, and topological properties investigated by density functional theory and/or molecular dynamics.

-engineering of Xenes: homo- and heterostructures, chemical functionalization, strain, doping.

-processing of Xenes : encapsulation, stabilization, layer transfer, patterning, etching.

-device integration of Xenes: electronic (FETs, memristors, capacitors, ...), photonic (phototransistors, detectors, plasmonic gratings, ...), flexible (strain gauges, e-tattoos, ...), and chemical (gas detectors, sensors, ...) devices.

Graphene and bilayer graphene, have since a while been identified as interesting hosts for spin and spin-valley qubits, thanks to their weak spin-orbit coupling and weak hyperfine interaction.
Bilayer graphene is attracting in particular increasing attention, as it presents a gate-tunable band gap, which can be used to electrostatically confine charge carriers into quantum point contacts and quantum dots (QDs)

In recent years gate-controlled single and double quantum dots in electrostatically gaped BLG attracted great interest and a remarkable degree of control in such devices has been shown.
Gate-defined quantum dots have been realized in bilayer graphene, allowing control of the occupation at the single-charge level and tunability from electron to hole occupation, the observation of spin and valley states as well as spin-valley coupling, and interdot coupling tunability in double-dot systems

The field is moving towards the implementation of spin and valley-qubits in graphene.

Topics will include but are not limited to:
Non-abelian quantum statistics.
Interferometry and quantum optics experiment.
Quantum Hall states and superconductivity.
Correlated insulator and superconductivity in quantum materials.

In CDW, electron-electron and electron-phonon interactions are simultaneously at play, with similar intensity thus making barely impossible to determine which is the actual driving force of the phase transition. In the years, time and angle resolved photoemission spectroscopy (trARPES) has contributed in isolating the two terms on the basis of their characteristic temporal scale, with momentum and energy resolution.

For this minicolloquium we propose a single slot of 2.5 hours to give space to 2-3 invited and 5-6 contributed talks delivered by leading experts in the field with the dual intent to discuss the breakthrough of novel families of CDW materials along with the impact of novel technological developments in trARPES. In fact, the recent advent of light source operating at several kHz 8 enables us to unveil the small modifications in the band structure that are at the origin of the CDW instability, while tunable pump energy allows to enhance the response of the lattice, thus efficiently restoring competing electronic and topological phases that are hidden by the CDW.

As their properties can be designed, customized and fabricated with increasing precision, now these devices are envisioned to detect mass, nuclear spins, radiation and temperature at the nanoscale [1-4]. Moreover, high-quality mechanical resonators are employed in several hybrid quantum systems, ranging from electromechanical and optomechanical [5] to quantum acoustic systems [6] in which the interactions between phonons and electrons or phonons and photons are exploited to transduce quantum information between different degrees of freedom.

Finally, nanomechanical systems constitute model systems for classical nonlinear dynamics with comparatively strong fluctuations. Hence, nanomechanical devices provide a means of exploring generic features of fluctuations in a driven system far from thermal equilibrium in a quantitative fashion [7-9]. These studies, in turn, lead to novel applications, as it is highly desirable to exploit nonlinearities in the mechanical domain in order to expand the functionality portfolio.

This mini-colloquium will serve to bring together the international research community engaged in fundamental research on micro- and nano- electromechanical systems as well as other hybrid, phononic nanoscale systems. It aims at gathering leading experts and young researchers on highly topical activities in this field, including among others: nonlinear dynamics, nonlinear dissipation, electromechanical systems, thermal and thermoelectrical effects in nanoresonators, noise sensing, nonlinear mode coupling, quantum hybrid and acoustic systems, and levitated nanosystems.

The mini-colloquium will consist of 6 to 8 invited talks and several slots for contributed talks. We will particularly encourage submissions from junior scientists, including graduate students, postdocs, and junior faculty.

The application of modified materials has been already exploited in many industrial processes such as ion-track nanotechnology, generation of nanopores in polymers, controlled drug delivery in biomedicine, etc. Modified 2D materials have applications in nanoelectronics, optoelectronics, spintronics etc.

This Mini-colloquium aims to provide an in-depth overview of the current status of understanding the modifications of structural, electronic, mechanical, magnetic, thermal, and optical properties of different types of materials (bulk and low dimensional structures) under ion beam irradiation, including both experiments and atomistic modelling contributions.

The scope of the Mini-colloquium will cover all aspects of fundamental experimental and theoretical research related to ion beam technology for material modification (from bulk to low-dimensional structure) such as ion implantation, ion channelling, highly charged and swift heavy ion irradiation. Particular attention will be devoted to the modification of electrical and optical properties of two-dimensional materials under mechanical deformations.

The mini-colloquium aims at uniting material scientists interested in glassy materials and liquid crystalline elastomers, in holographic information storage, and in probing material orientation and deformation in real time. This interdisciplinary topic would benefit a lot from insight into the key features that make this photomechanical behaviour happen, with applications in photonics, biology, surface engineering and robotics.

A wealth of physical processes and quantum phenomena can be explored, such as topological states, Floquet physics, coherent exciton Bose-Einstein condensation, and Exciton-Mott transition. In the early time-regime, coherent light−matter coupling can manifest through the dynamical Stark and Franz-Keldysh effects. Non coherent decay channels such Auger recombination, exciton-exciton annihilation, and exciton-phonon scattering dictate the excitons lifetime. Laser injected excitons can decay into finite momentum dark states. Excitonic complexes such as biexcitons, trions, and exciton-polarons can be involved in the process.

The understanding of these experiments requires advanced theoretical and computational methods. Dissipative mechanisms can be accounted for by non coherent rate equations. Coherent dynamics instead requires more fundamental approaches based on quantum equations. Two main challenges need to be tackled: (i) combine these approaches with accurate description of the materials properties; (ii) describe the transition from the coherent to the non coherent regime.

The goal of this mini-colloquium is to bring together researchers from different scientific communities, who study time-resolved exciton phenomena in functional materials. Within a joint cross-community meeting, we wish to encourage exchange of ideas and identify emerging questions for future research directions and collaborations.

CMD30 – FisMat2023 provides a unique environment to achieve interaction among scientists with broad spectrum of backgrounds (physics, biology and chemistry) that would not have registered for a highly specialized conference. Combination of work on naturally disordered matter and artificially tailored disorder may lead to new approaches for characterization of complex samples, modeling of light propagation or manufacturing of new materials.

Topics that shall be discussed in the mini-colloquium:
- microscopy and scattering-based diagnostics
- amorphous soft solids (gels, glasses, foams, granular media)
- biological systems (cells, tissues)
- 3D printing of photonic materials
- modeling of electromagnetic waves in disordered matter
- metrics and measures of disorder

The simultaneous breaking of time-reversal and inversion symmetry can lead to non-reciprocal charge transport. This is at the basis of conventional electronics, where the diode is based on the p-n junction. Only very recently it has been realized that the superconducting analogue of non-reciprocal transport can be made [3,4]. Such systems, showing a supercurrent diode effect (SDE), constitute a breakthrough for superconducting electronics. After the first experimental reports [3,4], several studies on SDE have been pursued very recently. High quality III-V semiconductors with an intrinsic strong SOC, such as InAs or InSb, in presence of sizable superconducting proximity become a natural platform to investigate SDE [4,5].

In addition, SOC together with superconductivity are key ingredients that can lead to the emergence of new states of matter and topological superconductivity [2,6,7]. A semiconductor nanowire with strong SOC in proximity to a superconductor has been predicted to host Majorana zero modes, which are expected to harbor non-Abelian statistics that would constitute a first element towards noise-resilient quantum computation [2,6]. Despite huge efforts in the search for topological signatures, this topic is still on the condensed matter agenda. Recent experimental advances in the realization of synthetic Kitaev chains based on quantum dots coupled via a superconductor open new avenues to realize a topological superconductor platform [8,9].

The mini-colloquium will bring together theorists and experimentalists to discussed topics including (but not limited to)
- coherence and dissipation in Josephson junctions and hybrid qubits and devices
- quantum measurement in superconducting circuits
- hybrid quantum circuits and quantum memories

Possible topics would include (but not limited to):
- 2-d materials
- Semiconducting nanowires
- Nano-carbon allotropes (graphene, nanoribbons, nanotubes, and so on)
- Colloidal semiconducting nanocrystals
- Nanoplasmonic hybridization
- Molecular switching systems
- Biosensing

In particular, the ability to exploit the quantum nature of a free-electron can reveal novel information not accessible with conventional schemes. In this colloquium, we will present recent methods for coherent wave function engineering, particularly exploiting the quantum interaction between electrons and photons. We will discuss how quantum manipulation of electrons can be used to implement new imaging methods and spectroscopic tools with novel and enhanced capabilities. Also, we will explore correlated quantum state dynamics in condensed matter and nano-photonics.

This colloquium, which is organized by the SMART-electron consortium (https://www.smartelectron.eu/), will be structured in four different sessions:
1. Quantum correlations in electron microscopy (chair: Ido Kaminer, TECHNION);
2. Electron beam shaping (chair: Vincenzo Grillo, CNR-Nano);
3. Recent progress in ultrafast electron microscopy and spectroscopy (chair: Fabrizio Carbone, EPFL);
4. Nanophotonics and ultrafast dynamics of materials (F. Javier García de Abajo, ICFO).
