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…
