Doubly chiral active Brownian particles with competing intrinsic rotation and translation-rotation coupling exhibit topologically protected boundary transport without backscattering, as shown by theory, simulation, and a vibrobot experiment.
In the bulk, away from boundaries, and for sufficiently low noise, such particles will typically undergo chiral orbits with radiusR bo =v/|ω|
