Abstract: An inertial Brownian motor under the influence of a biased biharmonic signal is investigated numerically. For a finite positive bias force, the maximized negative current occurs at a relatively large noise intensity (D=0.01), while the magnitude of the anomalous velocity is also very large (greater than 1.5). This result means one can observe remarkably abnormal transport behaviors at relatively high temperature by means of a biharmonic drive.
