Time-delayed feedback control of self-organized structures in dissipative systems — •Svetlana Gurevich¹, Felix Tabbert¹, and Alexander Kraft² — ¹Institut für Theoretische Physik, Universität Münster, Wilhelm-Klemm-Str.9, D-48149, Münster, Germany — ²Institut für Theoretische Physik, Technische Universität Berlin Hardenbergstr. 36 D-10623 Berlin

We are interested in the dynamical properties of periodic and localized structures in the Swift-Hohenberg equation subjected to a delayed feedback. We shall show that variation in the delay time and the feedback strength leads to the emergence of complex spatio-temporal patterns. In addition we show that the presence of spatial inhomogeneties strongly influences dynamical behavior of the system, resulting in the formation of intricate oscillatory structures.
