Directed transport in periodically rocked random sawtooth potentials

摘要

We study directed transport of overdamped particles in a periodically rocked random sawtooth potential.udTwo transport regimes can be identified which are characterized by a nonzero value of the average velocity ofudparticles and a zero value, respectively. The properties of directed transport in these regimes are investigatedudboth analytically and numerically in terms of a random sawtooth potential and a periodically varying drivingudforce. Precise conditions for the occurrence of transition between these two transport regimes are derived andudanalyzed in detail.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/2613
