Diffusion in Fluctuating Media: The Resonant Activation Problem
Jorge A. Revelli, Carlos. E. Budde, Horacio S. Wio
We present a one-dimensional model for diffusion in a fluctuating lattice; that is a lattice which can be in two or more states. Transitions between the lattice states are induced…
Strong enhancement of current, efficiency and mass separation in Brownian motors driven by non Gaussian noises
Sebastian Bouzat, Horacio S. Wio
We study a Brownian motor driven by a colored non Gaussian noise source with a -dependent probability distribution, where is a parameter indicating the departure from Gaussi…
Influence of Boundary Conditions on the Dynamics of Pattern Forming Systems: The Case of Oscillatory Media
S. Bouzat, H. S. Wio
We study the pattern dynamics in a reaction diffusion model of the activator--inhibitor type in the oscillatory regime. We consider finite systems with partially absorptive boundar…
"Fuzzy" stochastic resonance: robustness against noise tuning due to non Gaussian noises
M. A. Fuentes, C. Tessone, H. S. Wio +1
We have analyzed the phenomenon of stochastic resonance in a system driven by non Gaussian noises. We have considered both white and colored noises. In the latter case we have obta…
