Nonlocal-coupling-based control of stochastic resonance
Abstract
It is shown that nonlocal coupling provides for controlling the collective noise-induced dynamics in the regime of stochastic resonance. This effect is demonstrated by means of numerical simulation on an example of coupled overdamped bistable oscillators. In particular, it has been established that increasing the coupling radius and coupling strength allows to enhance or to suppress the effect of stochastic resonance which is reflected in the evolution of the dependence of the signal-to-noise ratio (SNR) on the noise intensity for varying coupling parameters. Nonlocal coupling is considered as an intermediate option between local and global (pairwise or higher-order interactions) coupling topologies which are also discussed in the context of the stochastic resonance control.
