Excitation Waves on a Minimal Small-World Model
Thomas Isele, Benedikt Hartung, Philipp Hövel +1
We examine traveling-wave solutions on a regular ring network with one additional long-range link that spans a distance d. The nodes obey the FitzHugh-Nagumo kinetics in the excita…
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…
Robustness of chimera states for coupled FitzHugh-Nagumo oscillators
Iryna Omelchenko, Astero Provata, Johanne Hizanidis +2
Chimera states are complex spatio-temporal patterns that consist of coexisting domains of spatially coherent and incoherent dynamics. This counterintuitive phenomenon was first obs…
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…
Front and Turing patterns induced by Mexican-hat-like nonlocal feedback
Julien Siebert, Eckehard Schöll
We consider the effects of a Mexican-hat-shaped nonlocal spatial coupling, i.e., symmetric long-range inhibition superimposed with short-range excitation, upon front propagation in…
