Fluctuation-induced transport in a spatially symmetric periodic potential
We present an analytical investigation of the fluctuation-induced transport of Brownian particles in a deterministic spatial symmetrical periodic potential subject to Gaussian noises. We found that directed motion of the Brownian particles can be induced by the correlation between a multiplicative white noise and an additive white noise. The direction of current is determined by the sign of the noise correlation.
