Cluster and splay states in networks of delay-coupled Stuart-Landau oscillators — •Chol-Ung Choe, Thomas Dahms, Philipp Hövel, and Eckehard Schöll — Institut f. Theo. Physik, Sekr. EW 7-1, Technische Universität Berlin, Hardenbergstr. 36, 10623 Berlin, Germany

We study one-dimensional ring and chain configurations of delay-coupled Stuart-Landau oscillators. The single elements are given by the complex normal form of supercritical Hopf bifurcation. Using the master stability function approach, we calculate the Floquet exponents of the synchronized state. Our simulations yield splay states or cluster dynamics, depending upon the chosen coupling delay.
