Transient chimera-like states for forced oscillators.

摘要: Chimera states occur widely in networks of identical oscillators as has been shown the recent extensive theoretical and experimental research. In such a state, different groups can exhibit coexisting synchronous incoherent behaviors despite homogeneous coupling. Here, we consider star network, which N peripheral end nodes are connected to central hub node. We find that if single node exhibits transient chaotic behavior whole pattern chimeralike persists for significant amount time, is created. As proof concept, examine system double pendula (peripheral nodes) located on periodically oscillating platform (central hub). show be observed simple experiments with mechanical oscillators, controlled by elementary dynamical equations. Our finding suggests observable relevant various real-world systems.
