Chimera states in networks of logistic maps with hierarchical connectivities
Alexander zur Bonsen, Iryna Omelchenko, Anna Zakharova +1
Chimera states are complex spatiotemporal patterns consisting of coexisting domains of coherence and incoherence. We study networks of nonlocally coupled logistic maps and analyze…
Chimera states in brain networks: empirical neural vs. modular fractal connectivity
Teresa Chouzouris, Iryna Omelchenko, Anna Zakharova +3
Complex spatiotemporal patterns, called chimera states, consist of coexisting coherent and incoherent domains and can be observed in networks of coupled oscillators. The interplay…
Coherence resonance in a network of FitzHugh-Nagumo systems: interplay of noise, time-delay and topology
Maria Masoliver, Nishant Malik, Eckehard Schöll +1
We systematically investigate the phenomena of coherence resonance in time-delay coupled networks of FitzHugh-Nagumo elements in the excitable regime. Using numerical simulations,…
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…
Time-delayed feedback control of coherence resonance chimeras
Anna Zakharova, Nadezhda Semenova, Vadim Anishchenko +1
Using the model of a FitzHugh-Nagumo system in the excitable regime we investigate the influence of time-delayed feedback on noise-induced chimera states in a network with nonlocal…
Chimera states in complex networks: interplay of fractal topology and delay
Jakub Sawicki, Iryna Omelchenko, Anna Zakharova +1
Chimera states are an example of intriguing partial synchronization patterns emerging in networks of identical oscillators. They consist of spatially coexisting domains of coherent…
Control of amplitude chimeras by time delay in dynamical networks
Aleksandar Gjurchinovski, Eckehard Schöll, Anna Zakharova
We investigate the influence of time-delayed coupling in a ring network of non-locally coupled Stuart-Landau oscillators upon chimera states, i.e., space-time patterns with coexist…
