Transient amplitude chimeras: the impact of time delay and noise — •Anna Zakharova¹, Julien Siebert¹, Sarah Loos¹, Aleksandar Gjurchinovski², and Eckehard Schöll¹ — ¹Institut für Theoretische Physik, Technische Universität Berlin, Germany — ²Institute of Physics, Faculty of Natural Sciences and Mathematics, Sts. Cyril and Methodius University, Skopje, Macedonia

For a network of Stuart-Landau oscillators with symmetry-breaking coupling we find chimera behavior with respect to amplitude dynamics rather than the phase (amplitude chimeras). We investigate the role of time delay and noise for these coherence-incoherence patterns. In more detail, we address the question of how time delay and noise influence the lifetime of transient amplitude chimeras.
