Abstract
We study the noise induced transport of an overdamped Brownian particle in frictional ratchet systems in the presence of a special class of external multiplicative Gaussian white noise fluctuations. The analytical expressions for current and diffusion coefficient are derived and the reliability or coherence of transport are discussed by means of their ratio. We show that these frictional ratchets exhibit larger coherence as compared to the flashing and rocking ratchets.
