Active Brownian particles in circular confinement accumulate at the boundary with positional power-law decay linked to curvature-induced bistable tangential orientations and stochastic switching between boundary-localized and bulk-mediated flips.

Origin of Persistent Boundary Motion in Confined Active Matter
Active Brownian particles in circular confinement accumulate at the boundary with positional power-law decay linked to curvature-induced bistable tangential orientations and stochastic switching between boundary-localized and bulk-mediated flips.
