Gain in stochastic resonance: Precise numerics versus linear response theory beyond the two-mode approximation
Casado Pascual, Jesús; Denk, Claus; Gómez Ordóñez, José; Morillo Buzón, Manuel; Hänggi, Peter (American Physical Society, 2003)In the context of the phenomenon of stochastic resonance (SR), we study the correlation function, the signal-to-noise ratio ...

Noise-induced forced synchronization of global variables in coupled bistable systems
Casado Vázquez, José Manuel; Gómez Ordóñez, José; Morillo Buzón, Manuel (IOP Publishing Ltd., 2007-09)We analyze the noise-induced synchronization between a collective variable characterizing a complex system with a finite ...

Theory of frequency and phase synchronization in a rocked bistable stochastic system
Casado Pascual, Jesús; Gómez Ordóñez, José; Morillo Buzón, Manuel; Lehmann, Jörg; Goychuk, Igor; Hänggi, Peter (American Physical Society, 2005)We investigate the role of noise in the phenomenon of stochastic synchronization of switching events in a rocked, overdamped ...
