The motion of a particle in a non-symmetric periodic potential of the form of triangles subject to periodic oscillations is studied. It turns out that a net flux appears as a result of oscillations of horizontally located barriers (ratchet effect). This flux as well as that in the case of inclined barriers are non-monotonic functions of the noise strength (stochastic resonance). © 2000 American Institute of Physics.

It is shown that a system with double symmetric cross advection produces the same characteristic...
