Noise-induced resonance , nonlinear

Noise is an inevitable feature of physical models. Theoretical and experimental research has recently shown that noise can have surprisingly constructive effects in many nonlinear systems. In particular, an optimal noise level may give rise to ordered behavior and even produce new dynamical states [11]. Well-known examples are provided by stochastic resonance [75, 76] in periodically driven systems, and by coherence resonance [10, 77, 78] in autonomous systems. In spite of considerable progress on a fundamental level, useful applications of noise-induced phenomena in technologically relevant devices are still scarce. Here we will demonstrate...
