We study the synchronization dynamics in a system of multiple interacting populations of phase oscillators.Using the dimensionality-reduction technique of Ott and Antonsen,we explore different types of synchronization dynamics when the incoherent state becomes unstable.We find that the inter-population coupling is crucial to the synchronization.When the intra-population interaction is repulsive,the local synchronization can still be maintained through the inter-population coupling.For attractive inter-population coupling,the local order parameters in different populations are of in-phase while the local synchronization are of anti-phase for repulsive inter-population coupling.
We study the synchronization dynamics in a system of multiple interacting populations of phase oscillators. Using the dimensionality-reduction technique of Ott and Antonsen, we explore different types of synchronization dynamics when the incoherent state becomes unstable. We find that the inter-population coupling is crucial to the synchronization. Where the intra-population interaction is repulsive, the local synchronization can still be maintained through the inter-population coupling. Forural inter-population coupling, the local order parameters in different populations are in-phase while the local synchronization are of anti-phase for repulsive inter-population coupling.
