Convergence of the Integral Fluctuation Theorem estimator for nonequilibrium Markov systems
Francesco Coghi, Lorenzo Buffoni, Stefano Gherardini
The Integral Fluctuation Theorem for entropy production (IFT) is among the few equalities that are known to be valid for physical systems arbitrarily driven far from equilibrium. M…
Adaptive power method for estimating large deviations in Markov chains
Francesco Coghi, Hugo Touchette
We study the performance of a stochastic algorithm based on the power method that adaptively learns the large deviation functions characterizing the fluctuations of additive functi…
Delocalization-localization dynamical phase transition of random walks on graphs
Giorgio Carugno, Pierpaolo Vivo, Francesco Coghi
We consider random walks evolving on two models of connected and undirected graphs and study the exact large deviations of a local dynamical observable. We prove, in the thermodyna…
Maximal dispersion of adaptive random walks
Gabriele Di Bona, Leonardo Di Gaetano, Vito Latora +1
Maximum entropy random walks (MERWs) are maximally dispersing and play a key role in optimizing information spreading in various contexts. However, building MERWs comes at the cost…
Graph-combinatorial approach for large deviations of Markov chains
Giorgio Carugno, Pierpaolo Vivo, Francesco Coghi
We consider discrete-time Markov chains and study large deviations of the pair empirical occupation measure, which is useful to compute fluctuations of pure-additive and jump-type…
