Repulsive torques alone trigger crystallization of constant speed active particles
arXiv:2204.06468 · doi:10.1039/D2SM00256F
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 determine the macroscopic phases of constant-speed active particles. This minimal model expands upon existing approaches for an improved understanding of crystallization of active matter.
