It is shown that, in the presence of spatial asymmetry, the asymmetry of the dichotomous noise can weaken or enhance the transport of the particles; while in the absence of spatial asymmetry, the nonzero current induced by the noise's asymmetry is "symmetric" around the zero current. In addition, a current reversal can be produced by controlling the noise's asymmetry parameter; and we find that, for some values of the noise's asymmetry parameter, the multiplicative dichotomous noise can more easily induce the transport of the particles than the additive dichotomous noise.Read More
