Phys. Rev. Lett. 93, 014102 (2004) [4 pages]Drift Motion, Phenomenon of Resonance, and Diffusive Motion Induced by a Chaotic SignalReceived 21 July 2003; published 29 June 2004 The effects of a quenched chaotic signal on the overdamped motion of a driven particle on a periodic, asymmetric potential are studied. It is shown that the chaotic signal can induce “drift” motion, the phenomenon of “resonance,” and “diffusion” motion. The possible applications to experiments on nanoscale surfaces and particle separation are discussed. © 2004 The American Physical Society URL:
