Inescapable anisotropy of non-reciprocal XY models
Dawid Dopierala, Hugues Chaté, Xia-qing Shi +1
We investigate non-reciprocal XY (NRXY) models defined on two-dimensional lattices in which the coupling strength of a spin with its neighbors varies with their position in the fra…
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…
Deterministic endless collective evolvement in active nematics
Xia-qing Shi, Yu-qiang Ma
We propose a simple deterministic dynamic equation and reveal the mechanism of large-scale endless evolvement of spatial density inhomogeneity in active nematic. We determine the p…
