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 …

Anti-aligning interaction between active particles induces a finite wavelength instability: The dancing hexagons

D Escaff - Physical Review E, 2024 - APS
By considering a simple model for self-propelled particle interaction, we show that anti-
aligning forces induce a finite wavelength instability. Consequently, the system exhibits …

Activity induced synchronization: Mutual flocking and chiral self-sorting

D Levis, I Pagonabarraga, B Liebchen - Physical Review Research, 2019 - APS
Synchronization, the temporal coordination of coupled oscillators, allows fireflies to flash in
unison, neurons to fire collectively, and human crowds to fall in step on the London …

Fluctuation-induced phase separation in metric and topological models of collective motion

D Martin, H Chaté, C Nardini, A Solon, J Tailleur… - Physical Review Letters, 2021 - APS
We study the role of noise on the nature of the transition to collective motion in dry active
matter. Starting from field theories that predict a continuous transition at the deterministic …

Thermodynamic uncertainty relation for underdamped Langevin systems driven by a velocity-dependent force

JS Lee, JM Park, H Park - Physical Review E, 2019 - APS
Recently, it has been shown that there is a trade-off relation between thermodynamic cost
and current fluctuations, referred to as the thermodynamic uncertainty relation (TUR). The …

Diffusion of active chiral particles

FJ Sevilla - Physical review E, 2016 - APS
The diffusion of chiral active Brownian particles in three-dimensional space is studied
analytically, by consideration of the corresponding Fokker-Planck equation for the …

Active motion on curved surfaces

P Castro-Villarreal, FJ Sevilla - Physical Review E, 2018 - APS
A theoretical analysis of active motion on curved surfaces is presented in terms of a
generalization of the telegrapher equation. Such a generalized equation is explicitly derived …

Emergence of nonwhite noise in Langevin dynamics with magnetic Lorentz force

HM Chun, X Durang, JD Noh - Physical Review E, 2018 - APS
We investigate the low mass limit of Langevin dynamics for a charged Brownian particle
driven by a magnetic Lorentz force. In the low mass limit, velocity variables relaxing quickly …

Self-organization of anti-aligning active particles: Waving pattern formation and chaos

D Escaff - Physical Review E, 2024 - APS
Recently, it has been shown that purely anti-aligning interaction between active particles
may induce a finite wavelength instability. The formed patterns display intricate …

Ordering kinetics and steady state of Malthusian flock

AP Jena, BS Mishra - Physics of Fluids, 2023 - pubs.aip.org
We study a collection of polar self-propelled particles or polar flock on a two dimensional
substrate involving birth and death. Most of the previous studies of polar flock with birth and …
