Repulsive torques alone trigger crystallization of constant speed active particles

Soft Matter, vol. 18, pp. 3120–3124

Abstract

We investigate the possibility for self-propelled particles to crystallize without reducing their intrinsic speed. We illuminate how, in the absence of any force, the competition between self-propulsion and repulsive torques determines the macroscopic phases of constant-speed active particles. This minimal model expands upon existing approaches for an improved understanding of crystallization of active matter.
