Abstract

Recently, we presented an experimental realization of a deterministic optical rocking ratchet [Arzola, A. V., et al. Phys Rev. Lett. 106: 168104 (2011)]. We obtained a systematic motion of microparticles and demonstrated that it is possible to control their average velocity and their direction of motion in real time by properly tuning experimental parameters. We have extended our study in order to establish the conditions for observing the crucial effect of current reversals in deterministic conditions, phenomenon predicted more than a decade ago, but experimentally demonstrated for the first time in our system.
