The mathematics behind chimera states

OE Omel'chenko - Nonlinearity, 2018 - iopscience.iop.org
Chimera states are self-organized spatiotemporal patterns of coexisting coherence and
incoherence. We give an overview of the main mathematical methods used in studies of …

Chimera state in complex networks of bistable Hodgkin-Huxley neurons

AV Andreev, NS Frolov, AN Pisarchik, AE Hramov - Physical Review E, 2019 - APS
In this paper we study a chimera state in complex networks of bistable Hodgkin-Huxley
neurons with excitatory coupling, which manifests as a termination of spiking activity of a part …

Smallest chimera states

Y Maistrenko, S Brezetsky, P Jaros, R Levchenko… - Physical Review E, 2017 - APS
We demonstrate that chimera behavior can be observed in small networks consisting of
three identical oscillators, with mutual all-to-all coupling. Three different types of chimeras …

Occurrence and stability of chimera states in coupled externally excited oscillators

D Dudkowski, Y Maistrenko… - Chaos: An Interdisciplinary …, 2016 - pubs.aip.org
We studied the phenomenon of chimera states in networks of non–locally coupled externally
excited oscillators. Units of the considered networks are bi–stable, having two co–existing …

Sample-based approach can outperform the classical dynamical analysis-experimental confirmation of the basin stability method

P Brzeski, J Wojewoda, T Kapitaniak, J Kurths… - Scientific reports, 2017 - nature.com
In this paper we show the first broad experimental confirmation of the basin stability
approach. The basin stability is one of the sample-based approach methods for analysis of …

Experimental observations of chimera states in locally and non-locally coupled Stuart-Landau oscillator circuits

LV Gambuzza, L Minati, M Frasca - Chaos, Solitons & Fractals, 2020 - Elsevier
Nontrivial spatiotemporal patterns emerge across many systems of interacting oscillators,
still the number of experimental investigations remains relatively limited. In this paper, we …

Chimera states in FitzHugh–Nagumo networks with reflecting connectivity

A Rontogiannis, A Provata - The European Physical Journal B, 2021 - Springer
We investigate the effects of reflecting connectivity in a network composed of FitzHugh–
Nagumo (FHN) elements linked in a ring topology. Reflecting connectivity is inspired by the …

Sample-based methods of analysis for multistable dynamical systems

P Brzeski, P Perlikowski - Archives of Computational Methods in …, 2019 - Springer
In this paper we present how sample based analysis can complement classical methods for
analysis of dynamical systems. We describe how sample based algorithms can be utilized to …

From Turing patterns to chimera states in the 2D Brusselator model

A Provata - Chaos: An Interdisciplinary Journal of Nonlinear …, 2023 - pubs.aip.org
The Brusselator has been used as a prototype model for autocatalytic reactions and, in
particular, for the Belousov–Zhabotinsky reaction. When coupled at the diffusive limit, the …

Dynamics of coupled Kuramoto oscillators with distributed delays

A Ross, SN Kyrychko, KB Blyuss… - … Journal of Nonlinear …, 2021 - pubs.aip.org
This paper studies the effects of two different types of distributed-delay coupling in the
system of two mutually coupled Kuramoto oscillators: one where the delay distribution is …
