The physicist's companion to current fluctuations: one-dimensional bulk-driven lattice gases

A Lazarescu - Journal of Physics A: Mathematical and …, 2015 - iopscience.iop.org
One of the main features of statistical systems out of equilibrium is the currents they exhibit in
their stationary state: microscopic currents of probability between configurations, which …

Sampling rare events across dynamical phase transitions

C Pérez-Espigares, PI Hurtado - Chaos: An Interdisciplinary Journal of …, 2019 - pubs.aip.org
Interacting particle systems with many degrees of freedom may undergo phase transitions to
sustain atypical fluctuations of dynamical observables such as the current or the activity. In …

Order and symmetry breaking in the fluctuations of driven systems

N Tizón-Escamilla, C Pérez-Espigares, PL Garrido… - Physical review …, 2017 - APS
Dynamical phase transitions (DPTs) in the space of trajectories are one of the most
intriguing phenomena of nonequilibrium physics, but their nature in realistic high …

Exact symmetries in the velocity fluctuations of a hot Brownian swimmer

G Falasco, R Pfaller, AP Bregulla, F Cichos, K Kroy - Physical Review E, 2016 - APS
Symmetries constrain dynamics. We test this fundamental physical principle, experimentally
and by molecular dynamics simulations, for a hot Janus swimmer operating far from thermal …

Isometric uncertainty relations

H Vroylandt, K Proesmans, TR Gingrich - Journal of Statistical Physics, 2020 - Springer
We generalize the link between fluctuation theorems and thermodynamic uncertainty
relations by deriving a bound on the variance of fluxes that satisfy an isometric fluctuation …

The kinetic exclusion process: a tale of two fields

C Gutiérrez-Ariza, PI Hurtado - Journal of Statistical Mechanics …, 2019 - iopscience.iop.org
We introduce a general class of stochastic lattice gas models, and derive their fluctuating
hydrodynamics description in the large size limit under a local equilibrium hypothesis. The …

Structure of the optimal path to a fluctuation

N Tizón-Escamilla, PI Hurtado, PL Garrido - Physical Review E, 2017 - APS
Macroscopic fluctuations have become an essential tool to understand physics far from
equilibrium due to the link between their statistics and nonequilibrium ensembles. The …

Coupled activity-current fluctuations in open quantum systems under strong symmetries

D Manzano, MA Martínez-García… - New Journal of …, 2021 - iopscience.iop.org
Strong symmetries in open quantum systems lead to broken ergodicity and the emergence
of multiple degenerate steady states. From a quantum jump (trajectory) perspective, the …

Symmetry-induced fluctuation relations for dynamical observables irrespective of their behavior under time reversal

S Marcantoni, C Pérez-Espigares, JP Garrahan - Physical Review E, 2020 - APS
We extend previous work to describe a class of fluctuation relations (FRs) that emerge as a
consequence of symmetries at the level of stochastic trajectories in Markov chains. We prove …

Weak additivity principle for current statistics in dimensions

C Pérez-Espigares, PL Garrido, PI Hurtado - Physical Review E, 2016 - APS
The additivity principle (AP) allows one to compute the current distribution in many one-
dimensional nonequilibrium systems. Here we extend this conjecture to general d …
