Generalized Landauer bound from absolute irreversibility
Lorenzo Buffoni, Francesco Coghi, Stefano Gherardini
In this work, we introduce a generalization of the Landauer bound for erasure processes that stems from absolutely irreversible dynamics. Assuming that the erasure process is carri…
Understanding random-walk dynamical phase coexistence through waiting times
David C. Stuhrmann, Francesco Coghi
We study the appearance of first-order dynamical phase transitions (DPTs) as `intermittent' co-existing phases in the fluctuations of random walks on graphs. We show that the diver…
Thermodynamic cost for precision of general counting observables
Patrick Pietzonka, Francesco Coghi
We analytically derive universal bounds that describe the trade-off between thermodynamic cost and precision in a sequence of events related to some internal changes of an otherwis…
Dynamical fluctuations of random walks in higher-order networks
Leonardo Di Gaetano, Giorgio Carugno, Federico Battiston +1
Although higher-order interactions are known to affect the typical state of dynamical processes giving rise to new collective behavior, how they drive the emergence of rare events…
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…
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…
