Abstract
The ratchet effect of an overdamped Brownian particle subjected to a spatially symmetric potential driven by a biharmonic temporal force is investigated when a non-Gaussian noise is considered. It is found that the noise intensity and the departure from the Gaussian noise will suppress the ratchet transport effect, while the noise color will strengthen the ratchet transport effect. In the same time, the phase difference mainly changes the direction of the transport. It is also shown that the abundant transport phenomenon is due to the breaking of symmetry for the biharmonic force.
