XY Model with Persistent Noise
Xia-qing Shi, Hugues Chaté, Benoît Mahault
We consider a 2D XY model subjected to time-correlated noise, a model of direct relevance to active crystals, which were shown recently to be able to support very large deformation…
Comment on "Flocking without Alignment Interactions in Attractive Active Brownian Particles [arXiv:2303.07746]"
Benoît Mahault
In a recent Letter, Caprini and Löwen argue that attractive active Brownian particles can flock even in the absence of explicit aligning interactions of their velocities. In this c…
Small Obstacle in a Large Polar Flock
Joan Codina, Benoît Mahault, Hugues Chaté +3
We show that arbitrarily large polar flocks are susceptible to the presence of a single small obstacle. In a wide region of parameter space, the obstacle triggers counter-propagati…
Breakdown of Ergodicity and Self-Averaging in Polar Flocks with Quenched Disorder
Yu Duan, Benoît Mahault, Yu-qiang Ma +2
We show that spatial quenched disorder affects polar active matter in ways more complex and far-reaching than believed heretofore. Using simulations of the 2D Vicsek model subjecte…
Dry, aligning, dilute, active matter: A synthetic and self-contained overview
Hugues Chaté, Benoît Mahault
These notes are based on lectures given during the Summer School `Active Matter and Nonequilibrium Statistical Physics', held in Les Houches in September 2018. Dry, aligning, dilut…
Deriving hydrodynamic equations from dry active matter models in three dimensions
Benoît Mahault, Aurelio Patelli, Hugues Chaté
We derive hydrodynamic equations from Vicsek-style dry active matter models in three dimensions (3D), building on our experience on the 2D case using the Boltzmann-Ginzburg-Landau…
