Brownian ratchets driven by flashing noise strengt
- 17 Downloads
The stochastic transport driven by flashing multi-noise sources in a ratchet is studied. The stationary current versus the noise strength and the colored noise correlated time r is obtained. At a fixed flip rate and strength of the colored noises, the novel phenomenon of the current reversal occurs as τ reaches a certain value. More than one reversal point exists when a flashing colored noise source and a flashing bdIite noise source are simultaneously taken into account.
