Abstract
Fluctuation-induced transport in a correlation ratchet driven by both additive Gaussian white and additive Ornstein-Uhlenbeck (colored) noise is studied numerically and interpreted against theoretical predictions. The current, as well as the current-load curve, exhibits a different behavior depending on the scaling of the colored noise strength. This archetypal correlation ratchet is capable of changing the direction of current (passing through zero at a particular value of noise color) if only the shape of the ratchet potential is chosen appropriately.Keywords
