Generalized optimal paths and weight distributions revealed through the large deviations of random walks on networks
Ricardo Gutiérrez, Carlos Pérez-Espigares
Numerous problems of both theoretical and practical interest are related to finding shortest (or otherwise optimal) paths in networks, frequently in the presence of some obstacles…
Symmetry-induced fluctuation relations for dynamical observables irrespective of their behaviour under time-reversal
Stefano Marcantoni, Carlos Pérez-Espigares, Juan P. Garrahan
We extend previous work to describe a class of fluctuation relations (FRs) that emerge as a consequence of symmetries at the level of stochastic trajectories in Markov chains. We p…
Entanglement statistics in Markovian open quantum systems: a matter of mutation and selection
Federico Carollo, Carlos Pérez-Espigares
Controlling dynamical fluctuations in open quantum systems is essential both for our comprehension of quantum nonequilibrium behaviour and for its possible application in near-term…
Sampling rare events across dynamical phase transitions
Carlos Pérez-Espigares, Pablo I. Hurtado
Interacting particle systems with many degrees of freedom may undergo phase transitions to sustain atypical fluctuations of dynamical observables such as the current or the activit…
