Solitary routes to chimera states
Leonhard Schülen, Alexander Gerdes, Matthias Wolfrum +1
We show how solitary states in a system of globally coupled FitzHugh-Nagumo oscillators can lead to the emergence of chimera states. By a numerical bifurcation analysis of a suitab…
Weak multiplexing in neural networks: Switching between chimera and solitary states
Maria Mikhaylenko, Lukas Ramlow, Sarika Jalan +1
We investigate spatio-temporal patterns occurring in a two-layer multiplex network of oscillatory FitzHugh-Nagumo neurons, where each layer is represented by a nonlocally coupled r…
Non-identical multiplexing promotes chimera states
Saptarshi Ghosh, Anna Zakharova, Sarika Jalan
We present the emergence of chimeras, a state referring to coexistence of partly coherent, partly incoherent dynamics in networks of identical oscillators, in a multiplex network c…
Double-well chimeras in 2D lattice of chaotic bistable elements
Igor A. Shepelev, Andrey A. Bukh, Tatiana E. Vadivasova +2
We investigate spatio-temporal dynamics of a 2D ensemble of nonlocally coupled chaotic cubic maps in a bistability regime. In particular, we perform a detailed study on the transit…
Birth and Death of Chimera: Interplay of Delay and Multiplexing
Saptarshi Ghosh, Anil Kumar, Anna Zakharova +1
The chimera state with co-existing coherent-incoherent dynamics has recently attracted a lot of attention due to its wide applicability. We investigate non-locally coupled identica…
Chimera patterns induced by distance-dependent power-law coupling in ecological networks
Tanmoy Banerjee, Partha Sharathi Dutta, Anna Zakharova +1
This paper reports the occurrence of several chimera patterns and the associated transitions among them in a network of coupled oscillators, which are connected by a long range int…
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…
Amplitude death in oscillator networks with variable-delay coupling
Aleksandar Gjurchinovski, Anna Zakharova, Eckehard Schöll
We study the conditions of amplitude death in a network of delay-coupled limit cycle oscillators by including time-varying delay in the coupling and self-feedback. By generalizing…
Time delay control of symmetry-breaking primary and secondary oscillation death
A. Zakharova, I. Schneider, Y. N. Kyrychko +4
We show that oscillation death as a specific type of oscillation suppression, which implies symmetry breaking, can be controlled by introducing time-delayed coupling. In particular…
