Delayed feedback control of noise-induced patterns in 1D excitable media — •Valentina Beato¹, Alexander Balanov¹, Natalia Janson², Harald Engel¹, and Eckehard Schöll¹ — ¹Institut für Theortische Physik, Technische Universtität Berlin, Hardenberstr. 36, Berlin 10623, Germany — ²Department of Mathematical Sciences, Loughborough University, Loughborough, Leicestershire, LE11 3TU, UK

We show that characteristic features of noise-induced spatio-temporal patterns can be effectively controlled using time delayed feedback. Actually, by variation of the time delay and the strength of the feedback one can deliberately change either the spatial or temporal coherence of noise-induced dynamics as well adjust its timescales.
