Stochastic ratchets

Abstract: Recent developments involving transport processes in simple nonlinear stochastic systems, i.e., active transport in fluctuating environments by so-called “ratchet” mechanisms, are briefly reviewed. In these systems, unoriented nonequilibrium fluctuations conspire with spatial anisotropy to generate directed motion. The fundamental principles of these phenomena are discussed, and some motivations for their study are described.
