Cooling mechanism controls motility-induced phase separation in inertial active liquids
Manuel Mayo, Lorenzo Caprini, MarÃa Isabel GarcÃa de Soria +4
Motility-induced phase separation (MIPS) is a central collective phenomenon in active matter, theoretically established in the overdamped regime. We discover that the dynamical ori…
