The possibility of investigating the dynamics of solids on timescales faster than the thermalization of the internal degrees of freedom  has disclosed novel non-equilibrium phenomena that have no counterpart at equilibrium. Transition metal oxides (TMOs) provide an interesting playground in which the correlations among the charges in the metal d-orbitals give rise to a wealth of intriguing electronic and thermodynamic properties involving the spin, charge, lattice and orbital orders. Furthermore, the physical properties of TMOs can be engineered at the atomic level, thus providing the platform to investigate the transport phenomena on timescales of the order of the intrinsic decoherence time of the charge excitations.
Here, we review and discuss two paradigmatic examples of transient emerging properties that are expected to open new fields of research:
i) the Mott-like reorganization of the high-energy electronic properties of copper oxides at the critical doping pcr≈0.16 . We will argue that the underdoped correlated state constitutes the fertile ground for the onset of low-temperature symmetry-breaking instabilities, such as the onset of charge-order.
ii) the possible preservation of the electronic quantum coherence on timescales of the order of the collection time in few-atomic layer devices . We will discuss the emergence of quantum-transport phenomena at ambient temperature in TMO-based heterostructures.
