Chiral active Brownian particles convert stored or environmental energy into both self-propulsion and autonomous rotation, driving systems far from equilibrium. Here, the authors combine experiments and theory to reveal a nonmonotonic diffusion enhancement in chiral active Brownian particles confined within an annular channel, driven by obstacle interactions, offering insights into nonequilibrium transport in biologically relevant settings.
