Structural anomalies in brain networks induce dynamical pacemaker effects
I. Koulierakis, D. A. Verganelakis, I. Omelchenko +3
Dynamical effects on healthy brains and brains affected by tumor are investigated via numerical simulations. The brains are modeled as multilayer networks consisting of neuronal os…
Effect of Topology upon Relay Synchronization in Triplex Neuronal Networks
Fenja Drauschke, Jakub Sawicki, Rico Berner +2
Relay synchronization in complex networks is characterized by the synchronization of remote parts of the network due to their interaction via a relay. In multilayer networks, dista…
Relay synchronization in multiplex networks of discrete maps
Marius Winkler, Jakub Sawicki, Iryna Omelchenko +3
Complex multiplex networks consist of several subnetwork layers, which interact via pairwise inter-layer connections. Relay synchronization between distant layers which are not dir…
Delay-induced chimeras in neural networks with fractal topology
Jakub Sawicki, Iryna Omelchenko, Anna Zakharova +1
We study chimera states, which are partial synchronization patterns consisting of spatially coexisting domains of coherent (synchronized) and incoherent (desynchronized) dynamics,…
Delay controls chimera relay synchronization in multiplex networks
Jakub Sawicki, Iryna Omelchenko, Anna Zakharova +1
We study remote (or relay) synchronization in multilayer networks between parts of one layer and their counterparts in a second layer, where these two layers are not directly conne…
Chimera states in quantum mechanics
V. M. Bastidas, I. Omelchenko, A. Zakharova +2
Classical chimera states are paradigmatic examples of partial synchronization patterns emerging in nonlinear dynamics. These states are characterized by the spatial coexistence of…
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…
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…
Chimera states in hierarchical networks of Van der Pol oscillators
Stefan Ulonska, Iryna Omelchenko, Anna Zakharova +1
Chimera states are complex spatio-temporal patterns that consist of coexisting domains of coherent and incoherent dynamics. We analyse chimera states in networks of Van der Pol osc…
A Tweezer for Chimeras in Small Networks
Iryna Omelchenko, Oleh E. Omel'chenko, Anna Zakharova +2
We propose a control scheme which can stabilize and fix the position of chimera states in small networks. Chimeras consist of coexisting domains of spatially coherent and incoheren…
Chimera states in population dynamics: networks with fragmented and hierarchical connectivities
Johanne Hizanidis, Evangelia Panagakou, Iryna Omelchenko +3
We study numerically the development of chimera states in networks of nonlocally coupled oscillators whose limit cycles emerge from a Hopf bifurcation. This dynamical system is ins…
Nonlinearity of local dynamics promotes multi-chimeras
Iryna Omelchenko, Anna Zakharova, Philipp Hoevel +2
Chimera states are complex spatio-temporal patterns in which domains of synchronous and asynchronous dynamics coexist in coupled systems of oscillators. We examine how the characte…
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…
