Chimeralike states in a network of oscillators under attractive and repulsive global coupling

The paper is for

Special Session is entitled "Chaotic and Complex Dynamics and its Applications"

We observe chimeralike states in networks of dynamical systems using a type of global coupling

consisting of two components: attractive and repulsive mean field feedback. We identify existence

of two types of chimeralike states in a bistable Lienard system; in one type, both the coherent

and the noncoherent populations are in chaotic states and, in the other type, the incoherent

population is in a periodic state while the coherent population is in periodic or chaotic and even

be quasiperiodic. We locate the coupling parameter regimes of the two types of chimerlike states

in a phase diagram. We study other bistable systems, a forced van der Pol-Duffing system and

the Josephson junction model to investigate generality of the coupling con_guration in creating

chimeralike states. We find chaos-chaos chimeralike states in the network of bistable van der Pol-

Duffing system, period-period chimeralike states in the network of Josephson junction model in the

bistable regime. Furthermore, we apply the coupling to a network of chaotic Rossler system where

we find the chaos-chaos chimeralike states.
