Description

In this talk, I will introduce the large deviation framework to study fluctuations of one and two-point observables of discrete-time Markov processes, which are useful to model dynamics and thermodynamics of equilibrium and nonequilibrium systems. I will restrict the analysis to the study of random walks on networks and, in particular, their spreading properties. I will show the appearance of a localisation-delocalisation dynamical phase transition as well as -- if time allows -- a minimal recipe to maximise the dispersion of a random walk that explores a network.
