Irreversibility and biased ensembles in active matter: Insights from stochastic thermodynamics

É Fodor, RL Jack, ME Cates - Annual Review of Condensed …, 2022 - annualreviews.org
Active systems evade the rules of equilibrium thermodynamics by constantly dissipating
energy at the level of their microscopic components. This energy flux stems from the …

Time irreversibility in active matter, from micro to macro

J O'Byrne, Y Kafri, J Tailleur, F van Wijland - Nature Reviews Physics, 2022 - nature.com
Active matter encompasses systems whose individual constituents dissipate energy to exert
propelling forces on their environment. These systems exhibit dynamical phenomena with …

Statistical mechanics of active Ornstein-Uhlenbeck particles

D Martin, J O'Byrne, ME Cates, É Fodor, C Nardini… - Physical Review E, 2021 - APS
We study the statistical properties of active Ornstein-Uhlenbeck particles (AOUPs). In this
simplest of models, the Gaussian white noise of overdamped Brownian colloids is replaced …

Irreversibility, heat and information flows induced by non-reciprocal interactions

SAM Loos, SHL Klapp - New Journal of Physics, 2020 - iopscience.iop.org
We study the thermodynamic properties induced by non-reciprocal interactions between
stochastic degrees of freedom in time-and space-continuous systems. We show that, under …

Deep learning probability flows and entropy production rates in active matter

NM Boffi, E Vanden-Eijnden - Proceedings of the National …, 2024 - National Acad Sciences
Active matter systems, from self-propelled colloids to motile bacteria, are characterized by
the conversion of free energy into useful work at the microscopic scale. They involve physics …

Hidden velocity ordering in dense suspensions of self-propelled disks

L Caprini, UMB Marconi, C Maggi, M Paoluzzi… - Physical Review …, 2020 - APS
Recent investigations of the phase diagram of spherical, purely repulsive, active particles
established the existence of a transition from a liquidlike to a solidlike phase analogous to …

Active Ornstein–Uhlenbeck model for self-propelled particles with inertia

GHP Nguyen, R Wittmann… - Journal of Physics …, 2021 - iopscience.iop.org
Self-propelled particles, which convert energy into mechanical motion, exhibit inertia if they
have a macroscopic size or move inside a gaseous medium, in contrast to micron-sized …

Information engine in a nonequilibrium bath

TK Saha, J Ehrich, M Gavrilov, S Still, DA Sivak… - Physical Review Letters, 2023 - APS
Information engines can convert thermal fluctuations of a bath at temperature T into work at
rates of order k BT per relaxation time of the system. We show experimentally that such …

Spatial velocity correlations in inertial systems of active Brownian particles

L Caprini, UMB Marconi - Soft Matter, 2021 - pubs.rsc.org
Recently, it has been discovered that systems of active Brownian particles (APB) at high
density organise their velocities into coherent domains showing large spatial structures in …

Entropy production fluctuations encode collective behavior in active matter

T GrandPre, K Klymko, KK Mandadapu, DT Limmer - Physical Review E, 2021 - APS
We derive a general lower bound on distributions of entropy production in interacting active
matter systems. The bound is tight in the limit that interparticle correlations are small and …
