Fluctuation Relations associated to an arbitrary bijection in path space
Raphael Chetrite, Stefano Marcantoni
We introduce a framework to identify Fluctuation Relations for vector-valued observables in physical systems evolving through a stochastic dynamics. These relations arise from the…
Martingales for physicists: A treatise on stochastic thermodynamics and beyond
Édgar Roldán, Izaak Neri, Raphael Chetrite +4
We review the theory of martingales as applied to stochastic thermodynamics and stochastic processes in physics more generally.
Anomalous heating in a colloidal system
Avinash Kumar, Raphael Chetrite, John Bechhoefer
We report anomalous heating in a colloidal system, the first observation of the inverse Mpemba effect, where an initially cold system heats up faster than an identical warm system…
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…
Periodically driven jump processes conditioned on large deviations
Lydia Chabane, Raphaël Chétrite, Gatien Verley
We study the fluctuations of systems modeled by Markov jump processes with periodic generators. We focus on observables defined through time-periodic functions of the system's stat…
Information thermodynamics for interacting stochastic systems without bipartite structure
R. Chétrite, M. L. Rosinberg, T. Sagawa +1
Fluctuations in biochemical networks, e.g., in a living cell, have a complex origin that precludes a description of such systems in terms of bipartite or multipartite processes, as…
