Genesis of chimera patterns through self-induced stochastic resonance

Noise induced order in excitable systems has diverse manifestations, such as coherence resonance (CR) and stochastic resonance. In this context a less explored phenomenon is self-induced (SISR). Unlike CR, SISR may arise away from the bifurcation threshold properties of oscillations depend upon both noise intensity time-scale separation factor. work, we report new chimera pattern network coupled units, namely or SISR-chimera that originates phenomenon. We explore detailed dynamics parameter space using proper quantitative measures. observe unlike CR chimera, strongly depends ratio time scale intensity. Therefore, type can be even for tiny if activator inhibitor large enough.
