Chimera states in chemical relaxation oscillators — •Julian Rode, Jan Totz, and Harald Engel — Technische Universität Berlin, Berlin

A system of identical oscillators with an identical coupling can differentiate in a synchronized and a desynchronized part, the so called chimera state [1]. Experiments on various chemical and physical systems have confirmed its existence [2]. We study the simplest scenario first: Ideal phase oscillators on a ring network. Inspired by real world oscillators like nerve cells, we take one further step and numerically explore chimera states on relaxation oscillators, which we compare with our experimental findings.
