Long-Range Nematic Order in Two-Dimensional Active Matter
Benoît Mahault, Hugues Chaté
Working in two space dimensions, we show that the orientational order emerging from self-propelled polar particles aligning nematically is quasi-long-ranged beyond ,…
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…
Self-Organized Critical Coexistence Phase in Repulsive Active Particles
Xia-qing Shi, Giordano Fausti, Hugues Chaté +2
We revisit motility-induced phase separation in two models of active particles interacting by pairwise repulsion. We show that the resulting dense phase contains gas bubbles distri…
Quantitative Assessment of the Toner and Tu Theory of Polar Flocks
Benoît Mahault, Francesco Ginelli, Hugues Chaté
We present a quantitative assessment of the Toner and Tu theory describing the universal scaling of fluctuations in polar phases of dry active matter. Using large scale simulations…
Convergence of Non-Perturbative Approximations to the Renormalization Group
Ivan Balog, Hugues Chaté, Bertrand Delamotte +2
We provide analytical arguments showing that the non-perturbative approximation scheme to Wilson's renormalisation group known as the derivative expansion has a finite radius of co…
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…
