Chimera dynamics in an array of coupled FitzHugh-Nagumo system with shift of close neighbors

摘要

In this paper, we consider an array of FitzHugh-Nagumo (FHN) systems with close neighbors. Each element ( ) connects to another ( ) and its 2 neighbors. Shifting these neighbors produces particular phenomena such as chimera and multi-chimera. Step traveling chimera is observed for a time dependent shift. Results show that, basing oneself on both shift parameter and close neighbors , a full control on the chimera dynamics of the network can be ensured.
