In systems possessing a spatial or dynamical symmetry breaking, thermal Brownian motion combined with unbiased, non-equilibrium noise gives rise to a channelling of chance that can be used to exercise control over systems at the micro-and even on the nano-scale. This theme is known as the "Brownian
The biased movement of Brownian particles on a #uctuating two-state periodic potential made of identical distorted ratchets is studied. The purpose is to investigate how the direction of the particle movement is related to the asymmetry of the potential. In general, distorting one of the two linear
