Clustering and phase resetting in a chain of bistable nonisochronous oscillators

Abstract

We consider a chain with many locally coupled bistable nonisochronous oscillators. We show that on the "background" of a disordered amplitude distribution either phase or frequency clusters form in the chain. Cluster location varies according to the amplitude distribution. In the case of frequency clusters their interaction leads to phase resetting in an isolated oscillator located between two neighboring frequency clusters.
