Symmetry-induced fluctuation relations in open quantum systems
Stefano Marcantoni, Carlos Pérez-Espigares, Juan P. Garrahan
We derive a general scheme to obtain quantum fluctuation relations for dynamical observables in open quantum systems. For concreteness we consider Markovian non-unitary dynamics th…

Dynamical criticality in open systems: non-perturbative physics, microscopic origin and direct observation
Carlos Pérez-Espigares, Federico Carollo, Juan P. Garrahan +1
Driven diffusive systems may undergo phase transitions to sustain atypical values of the current. This leads in some cases to symmetry-broken space-time trajectories which enhance…

Glassy dynamics due to a trajectory phase transition in dissipative Rydberg gases
Carlos Pérez-Espigares, Igor Lesanovsky, Juan P. Garrahan +1
The physics of highly excited Rydberg atoms is governed by blockade or exclusion interactions that hinder the excitation of atoms in the proximity of a previously excited one. This…
