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 کاملSpatiotemporal coherence resonance of phase synchronization in weakly coupled chaotic oscillators.
We study phase synchronization (PS) of coupled chaotic oscillators as a result of an interplay between local coupling and global noise. In the weak coupling region, noise first significantly enhances spatiotemporal PS, but it spoils the phase coherence of chaotic oscillation and reduces the degree of synchronization at large intensities. The spatiotemporal behavior exhibits coherence resonance....
متن کاملCoherence resonance near the Hopf bifurcation in coupled chaotic oscillators.
We uncover a coherence resonance near the Hopf bifurcation from chaos in coupled chaotic oscillators. At the bifurcation, a nearly periodic rotating wave becomes stable as the state of synchronous chaos is destabilized. We find that noise can induce the bifurcation and, more strikingly, it can enhance the temporal regularity of the wave pattern in the coupled system. This resonant phenomenon is...
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...
متن کاملDeterministic coherence resonance in coupled chaotic oscillators with frequency mismatch.
A small mismatch between natural frequencies of unidirectionally coupled chaotic oscillators can induce coherence resonance in the slave oscillator for a certain coupling strength. This surprising phenomenon resembles "stabilization of chaos by chaos," i.e., the chaotic driving applied to the chaotic system makes its dynamics more regular when the natural frequency of the slave oscillator is a ...
