Current fluctuations in classical and quantum systems far from equilibrium
In this talk we will review some results derived from the study of current fluctuations in non-equilibrium diffusive systems. We will show how by applying the Macroscopic Fluctuation Theory (MFT), interesting properties such as dynamical phase transitions, emerge. In addition, recent results concerning the applicability of the MFT to boundary-driven open quantum systems will be derived, where fermionic open chains display a third-order dynamical phase transition similar to that of classical exclusion processes with open boundaries. We show that this transition is manifested in a singular change in the structure of trajectories: while typical trajectories are diffusive, rare trajectories associated to atypical currents are ballistic and hyperuniform in their spatial structure.
