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…
Current fluctuations in a stochastic system of classical particles with next-nearest-neighbor interactions
Sara Kaviani, Farhad H. Jafarpour
A totally asymmetric exclusion process consisting of classical particles with next-nearest-neighbor interactions has been considered on a 1D discrete lattice with a ring geometry.…
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…
A rare event algorithm links transitions in turbulent flows with activated nucleations
Freddy Bouchet, Joran Rolland, Eric Simonnet
Many turbulent flows undergo drastic and abrupt configuration changes with huge impacts. As a paradigmatic example we study the multistability of jet dynamics in a barotropic beta…
Bounds on current fluctuations in periodically driven systems
Andre C Barato, Raphael Chetrite, Alessandra Faggionato +1
Small nonequilibrium systems in contact with a heat bath can be analyzed with the framework of stochastic thermodynamics. In such systems, fluctuations, which are not negligible, f…
Current fluctuations in periodically driven systems
Andre C Barato, Raphael Chetrite
Small nonequelibrium systems driven by an external periodic protocol can be described by Markov processes with time-periodic transition rates. In general, current fluctuations in s…
Stochastic control in microscopic nonequilibrium systems
Steven J. Large, Raphaël Chetrite, David A. Sivak
Quantifying energy flows at nanometer scales promises to guide future research in a variety of disciplines, from microscopic control and manipulation, to autonomously operating mol…
Trapping scaling for bifurcations in Vlasov systems
J. Barré, D. Métivier, Y. Y. Yamaguchi
We study non oscillating bifurcations of non homogeneous steady states of the Vlasov equation, a situation occurring in galactic models, or for Bernstein-Greene-Kruskal modes in pl…
Variational and optimal control representations of conditioned and driven processes
Raphael Chetrite, Hugo Touchette
We have shown recently that a Markov process conditioned on rare events involving time-integrated random variables can be described in the long-time limit by an effective Markov pr…
Superdiffusion, large-scale synchronization and topological defects
Robert Großmann, Fernando Peruani, Markus Bär
We study an ensemble of random walkers carrying internal noisy phase oscillators which are synchronized among the walkers by local interactions. Due to individual mobility, the int…
A formal view on 2.5 large deviations and fluctuation relations
Andre C. Barato, Raphael Chetrite
We obtain the rate function for the level 2.5 of large deviations for pure jump and diffusion processes. This result is proved by two methods: tilting, for which a tilted process w…
3/4 Fractional superdiffusion of energy in a system of harmonic oscillators perturbed by a conservative noise
Cedric Bernardin, Patricia Gonçalves, Milton Jara
We consider a harmonic chain perturbed by an energy conserving noise and show that after a space-time rescaling the energy-energy correlation function is given by the solution of a…
Symmetry Breaking in d-Dimensional Self-gravitating Systems
Renato Pakter, Bruno Marcos, Yan Levin
Systems with long-range interactions, such as self-gravitating clusters and magnetically confined plasmas, do not relax to the usual Boltzmann-Gibbs thermodynamic equilibrium, but…
Classical Heisenberg spins with long-range interactions: Relaxation to equilibrium for finite systems
Julien Barré, Shamik Gupta
Systems with long-range interactions often relax towards statistical equilibrium over timescales that diverge with , the number of particles. A recent work [S. Gupta and D. Muka…
Nonequilibrium microcanonical and canonical ensembles and their equivalence
Raphael Chetrite, Hugo Touchette
Generalizations of the microcanonical and canonical ensembles for paths of Markov processes have been proposed recently to describe the statistical properties of nonequilibrium sys…
The microscopic phase density functional approach to the construction of the kinetic and hydrodynamic description for the system of self-propelled particles
Oleksandr Chepizhko, Vladimir Kulinskii
We use the method of the microscopic phase density to get the kinetic equation for the system of self-propelled particles with Vicsek-like alignment rule. The hydrodynamic equation…
A kinetic model and scaling properties for non-equilibrium clustering of self-propelled particles
Fernando Peruani, Markus Baer
We demonstrate that the clustering statistics and the corresponding phase transition to non-equilibrium clustering found in many experiments and simulation studies with self-propel…
Collisional relaxation of two-dimensional self-gravitating systems
B. Marcos
Systems with long range interactions present generically the formation of quasi-stationary long-lived non-equilibrium states. These states relax to Boltzmann equilibrium following…
Anomalous fluctuations for a perturbed Hamiltonian system with exponential interactions
Cedric Bernardin, P. Gonçalves
A one-dimensional Hamiltonian system with exponential interactions perturbed by a conservative noise is considered. It is proved that energy superdiffuses and upper and lower bound…
Inequalities generalizing the second law of thermodynamics for transitions between non-stationary states
Gatien Verley, Raphaël Chétrite, David Lacoste
We discuss the consequences of a variant of the Hatano-Sasa relation in which a non-stationary distribution is used in place of the usual stationary one. We first show that this no…
Quantum Fluctuation Relations for the Lindblad Master Equation
Raphael Chetrite, Kirone Mallick
An open quantum system interacting with its environment can be modeled under suitable assumptions as a Markov process, described by a Lindblad master equation. In this work, we der…
Combinatorial models of rigidity and renormalization
Julien Barré
We first introduce the percolation problems associated with the graph theoretical concepts of -sparsity, and make contact with the physical concepts of ordinary and rigidity…
A Gallavotti-Cohen-Evans-Morriss like symmetry for a class of Markov jump processes
Andre Cardoso Barato, Raphael Chetrite, Haye Hinrichsen +1
We investigate a new symmetry of the large deviation function of certain time-integrated currents in non-equilibrium systems. The symmetry is similar to the well-known Gallavotti-C…

Gatien Verley, Raphaël Chétrite, David Lacoste
In this paper, we present a general derivation of a modified fluctuation-dissipation theorem (MFDT) valid near an arbitrary non-stationary state for a system obeying markovian dyna…
