A random walker on a ratchet potential: Effect of a non Gaussian noise
Sergio E. Mangioni, Horacio S. Wio
We analyze the effect of a colored non Gaussian noise on a model of a random walker moving along a ratchet potential. Such a model was motivated by the transport properties of moto…
Stochastic resonance between dissipative structures in a bistable noise-sustained dynamics
B. von Haeften, G. Izús, S. Mangioni +2
We study an extended system that without noise shows a monostable dynamics, but when submitted to an adequate multiplicative noise, an effective bistable dynamics arise. The stocha…
Stochastic resonance between noise-sustained patterns
B. von Haeften, G. Izús, S. Mangioni +2
We study an extended system that without noise shows a spatially homogeneous state, but when submitted to an adequate multiplicative noise, some "noise-induced patterns" arise. The…
A Fokker--Planck description for Parrondo's games
R. Toral, P. Amengual, S. Mangioni
We discuss in detail two recently proposed relations between the Parrondo's games and the Fokker--Planck equation describing the flashing ratchet as the overdamped motion of a part…
Limit cycle induced by multiplicative noise in a system of coupled Brownian motors
Sergio Mangioni, Horacio S. Wio
We study a model consisting of nonlinear oscillators with {\em global periodic} coupling and {\em local multiplicative} and additive noises. The model was shown to undergo a no…
Parrondo's games as a discrete ratchet
Raul Toral, Pau Amengual, Sergio Mangioni
We write the master equation describing the Parrondo's games as a consistent discretization of the Fokker--Planck equation for an overdamped Brownian particle describing a ratchet.…
