Coherence resonance in coupled chaotic oscillators.
Existing works on coherence resonance, i.e., the phenomenon of noise-enhanced temporal regularity, focus on excitable dynamical systems such as those described by the FitzHugh-Nagumo equations. We extend the scope of coherence resonance to an important class of dynamical systems: coupled chaotic oscillators. In particular, we show that, when a system of coupled chaotic oscillators is under the ...
متن کاملPeriodic Orbits of Coupled Oscillators Near Resonance
A persistence theorem for xed points of a parameterized family of maps is specialized to give a method for detecting the existence of persistent periodic solutions of perturbed systems of di erential equa tions in particular systems of weakly coupled planar oscillators An application is make to the problem of synchronization of two detuned and weakly inductively coupled van der Pol oscillators
متن کاملSynchronization and resonance in a driven system of coupled oscillators.
We study the noise effects in a driven system of globally coupled oscillators, with particular attention to the interplay between driving and noise. The self-consistency equation for the order parameter, which measures the collective synchronization of the system, is derived; it is found that the total order parameter decreases monotonically with noise, indicating overall suppression of synchro...
متن کاملCoherence resonance and polymodality in inhibitory coupled excitable oscillators.
We have analyzed the firing activity of two and three excitable FitzHugh-Nagumo oscillators, coupled via slow variable diffusion and under the action of an external noise. We find a different form of coherence resonance in this system, which is, in contrast to previous studies, intrinsically based on the antiphase behavior of coupled elements. Additionally, we show that an exchange, performed b...
