Mobility-induced persistent chimera states

TL;DR

This paper investigates how mobility and coupling delays in identical oscillators lead to persistent chimera states, revealing complex coexistence of synchronized and incoherent domains with potential relevance to natural and technological systems.

Contribution

It introduces the concept of mobility-induced chimera states in oscillators with coupling delays, highlighting their persistence and the mechanisms behind their formation across mobility regimes.

Findings

Chimera states coexist with in-phase and anti-phase domains.

Persistent chimera states occur at intermediate mobility levels.

Mechanisms for chimera formation depend on mobility regimes.

Abstract

We study the dynamics of mobile, locally coupled identical oscillators in the presence of coupling delays. We find different kinds of chimera states, in which coherent in-phase and anti-phase domains coexist with incoherent domains. These chimera states are dynamic and can persist for long times for intermediate mobility values. We discuss the mechanisms leading to the formation of these chimera states in different mobility regimes. This finding could be relevant for natural and technological systems composed of mobile communicating agents.
