Curvature-driven wall accumulation in chiral active particles
Alessandro Petrini, Raphaël Maire, Umberto Marini Bettolo Marconi +1
We study a dilute system of non-motile chiral active particles confined in geometries ranging from straight channels to circular enclosures. Activity is introduced through chiral p…
Sparkling bubbles in chiral active fluids
Alessandro Petrini, Raphaël Maire, Umberto Marini Bettolo Marconi +1
We study an inertial chiral active fluid, formed by repulsive particles that transfer angular momentum through odd interactions, i.e. transverse forces. Chirality induces an inhomo…
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…
Active thermodynamics of inertial chiral active gases: equation of state and edge currents
Lorenzo Caprini, Umberto Marini Bettolo Marconi, Benno Liebchen +1
One of the most fundamental quests in the physics of active matter concerns the existence of a comprehensive theory for its macroscopic properties, i.e. an ``active thermodynamics'…
