Metastability and nucleation of bubbles in active chiral systems
Raphael Maire, Alessandro Petrini, Umberto Marini Bettolo Marconi +1
Bubbles frequently emerge in dense chiral active fluids, yet it remains unclear whether they result from an instability of the homogeneous state or from rare nucleation events with…
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…
