Time-delayed feedback control of coherence resonance near subcritical Hopf bifurcation: theory versus experiment
V. Semenov, A. Feoktistov, T. Vadivasova +2
Using the model of a generalized Van der Pol oscillator in the regime of subcritical Hopf bifurcation we investigate the influence of time delay on noise-induced oscillations. It i…
Amplitude-phase coupling drives chimera states in globally coupled laser networks
Fabian Böhm, Anna Zakharova, Eckehard Schöll +1
For a globally coupled network of semiconductor lasers with delayed optical feedback, we demonstrate the existence of chimera states. The domains of coherence and incoherence that…
Partial Synchronization and Partial Amplitude Death in Mesoscale Network Motifs
Winnie Poel, Anna Zakharova, Eckehard Schöll
We study the interplay between network topology and complex space-time patterns and introduce a concept to analytically predict complex patterns in networks of Stuart-Landau oscill…
Modulating coherence resonance in non-excitable systems by time-delayed feedback
Paul M. Geffert, Anna Zakharova, Andrea Vüllings +2
We propose a paradigmatic model system, a subcritical Hopf normal form subjected to noise and time-delayed feedback, to investigate the impact of time delay on coherence resonance…
Chimera Death: Symmetry Breaking in Dynamical Networks
Anna Zakharova, Marie Kapeller, Eckehard Schöll
For a network of generic oscillators with nonlocal topology and symmetry-breaking coupling we establish novel partially coherent inhomogeneous spatial patterns, which combine the f…
