Abstract
We consider diffusive motion on a periodic, anisotropic potential. Multiplicative three-state noise can bring about net flow. As the speed of this noise varies, the direction of the flux can change. We explain the flux reversals and discuss a possible application for the construction of a device for the separation of small particles.Keywords
