Current reversals in a rocking ratchet: dynamical vs symmetry-breaking mechanisms
arXiv:1005.3385 · doi:10.1103/PhysRevE.82.041116
Abstract
Directed transport in ratchets is determined by symmetry-breaking in a system out of equilibrium. A hallmark of rocking ratchets is current reversals: an increase in the rocking force changes the direction of the current. In this work for a bi-harmonically driven spatially symmetric rocking ratchet we show that a class of current reversal is precisely determined by symmetry-breaking, thus creating a link between dynamical and symmetry-breaking mechanisms.
