Abstract
The effects of quenched disorder on the overdamped motion of a driven particle on a periodic, asymmetric potential are studied. While for the unperturbed potential the transport is due to a regular drift, the quenched disorder induces a significant additional chaotic “diffusive” motion. Possible applications to experiments in nanoscale surfaces and particle separation are discussed.Keywords
