Pattern formation in Swift-Hohenberg equation with delayed feedback — •Alexander Kraft and Svetlana Gurevich — Institut for Theoretical Physics, Wilhelm-Klemm-Str. 9, 48149 Münster

We are interested in the stability of periodic patterns in a real Swift-Hohenberg equation subjected to a delayed feedback. We classify different stability regimes of homogeneous solution and discuss how the delayed feedback modifies the stability of periodic patterns. In particular, we show that the delayed feedback induces a spontaneous motion of periodic patterns and leads to the formation of complex structures, including, e.g., traveling zigzag patterns and hexagons.
