Role of current fluctuations in nonreversible samplers
Francesco Coghi, Raphael Chetrite, Hugo Touchette
It is known that the distribution of nonreversible Markov processes breaking the detailed balance condition converges faster to the stationary distribution compared to reversible p…
A large deviation perspective on ratio observables in reset processes: robustness of rate functions
Francesco Coghi, Rosemary J. Harris
We study large deviations of a ratio observable in discrete-time reset processes. The ratio takes the form of a current divided by the number of reset steps and as such it is not e…
Large deviations of random walks on random graphs
Francesco Coghi, Jules Morand, Hugo Touchette
We study using large deviation theory the fluctuations of time-integrated functionals or observables of the unbiased random walk evolving on Erdös-Rényi random graphs, and construc…
Controlling the uncertain response of real multiplex networks to random damage
Francesco Coghi, Filippo Radicchi, Ginestra Bianconi
We reveal large fluctuations in the response of real multiplex networks to random damage of nodes. These results indicate that the average response to random damage, traditionally…
