Shape-anisotropy inverses the behavior of emergent vortices in active chiral fluids

Abstract Active colloidal fluids exhibit spontaneous emergence of correlated states, characterized by complex collective dynamics and self-organization. In geometrically confined systems, activity modulations trigger robust polar state reversals of a macroscopic vortex formed by colloidal rollers. H...
