Synchronization of heterogeneous chemical relaxation oscillators — •Jan Frederik Totz1, Julian Rode1, Kenneth Showalter2, and Harald Engel1 — 1Technische Universität Berlin, Berlin, Germany — 2West Virginia University, Morgantown, USA
Recently discovered synchronization patterns, such as chimera states and intertwined cluster synchronization in networks of identical nonlinear oscillators lead to the emergence of new theoretical concepts, most notably an extended master stability function for networks with permutation symmetries [1].
Optically coupled catalytic beads provide a versatile experimental tool to study the emergence of collective synchronization patterns with real oscillators under well-controlled laboratory conditions [2].
One important aspect is the impact of a broad oscillator frequency distribution. Instead of in-phase or cluster synchronization, experiments reveal phase wave synchronization through neighboring permutation symmetry clusters [3].
