Quantifying the transition from spiral waves to spiral wave chimeras in a lattice of self-sustained oscillators
I. A. Shepelev, A. V. Bukh, S. S. Muni +1
The present work is devoted to the detailed quantification of the transition from spiral waves to spiral wave chimeras in a network of self-sustained oscillators with two-dimension…
Role of solitary states in forming spatiotemporal patterns in a 2D lattice of van der Pol oscillators
I. A. Shepelev, A. V. Bukh, S. S. Muni +1
The behavior of the ensemble of coupled van der Pol oscillators is abundant when coupling parameters are changed. Incoherent and chimera-like regimes are observed at small values o…
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…
Mechanism of solitary state appearance in an ensemble of nonlocally coupled Lozi maps
Nadezhda Semenova, Tatyana Vadivasova, Vadim Anishchenko
We study the peculiarities of the solitary state appearance in the ensemble of nonlocally coupled chaotic maps. We show that nonlocal coupling and features of the partial elements…
External and mutual synchronization of chimeras in a two layer network of nonlinear oscillators
Andrei V. Bukh, Galina I. Strelkova, Vadim S. Anishchenko
We study numerically synchronization phenomena of spatiotemporal structures, including chimera states, in a two layer network of nonlocally coupled nonlinear chaotic discrete-time…

Andrei Bukh, Elena Rybalova, Nadezhda Semenova +2
We study numerically the dynamics of a network made of two coupled one-dimensional ensembles of discrete-time systems. The first ensemble is represented by a ring of nonlocally cou…
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…
New type of chimera structures in a ring of bistable FitzHugh-Nagumo oscillators with nonlocal interaction
Igor A. Shepelev, Tatiana E. Vadivasova, Galina. I. Strelkova +1
We study the spatiotemporal dynamics of a ring of nonlocally coupled FitzHugh-Nagumo oscillators in the bistable regime. A new type of chimera patterns has been found in the noise-…
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…
Noise-induced chimera states in a neural network
Anna Zakharova, Nadezhda Semenova, Vadim Anishchenko +1
We show that chimera patterns can be induced by noise in nonlocally coupled neural networks in the excitable regime. In contrast to classical chimeras, occurring in noise-free osci…
Coherence-resonance chimeras in a network of excitable elements
Nadezhda Semenova, Anna Zakharova, Vadim Anishchenko +1
We demonstrate that chimera behavior can be observed in nonlocally coupled networks of excitable systems in the presence of noise. This phenomenon is distinct from classical chimer…
Noise-induced transitions in a double-well oscillator with nonlinear dissipation
Vladimir V. Semenov, Alexander B. Neiman, Tatyana E. Vadivasova +1
We develop a model of bistable oscillator with nonlinear dissipation. Using a numerical simulation and an electronic circuit realization of this system we study its response to add…

Boris Shulgin, Alexander Neiman, Vadim Anishchenko
The nonlinear response of noisy bistable systems driven by strong amplitude periodical force is investigated by physical experiment. The new phenomenon of locking of the mean switc…
