Time-delayed feedback control of noise-induced patterns — •Eckehard Schöll, Alexander Balanov, Johanne Hizanidis, and Grischa Stegemann — Institut für Theoretische Physik, Technische Universität Berlin, 10623 Berlin

Effects of time-delayed feedback on spatio-temporal patterns induced by Gaussian white noise are studied. It is shown that such a feedback in the form proposed earlier by Pyragas for the control of deterministic chaos can be used for effective manipulation of the coherence and the timescales of stochastically oscillating patterns. This is illustrated for globally coupled reaction-diffusion systems.
