Nonlocal-coupling-based control of coherence resonance
Aleksey Ryabov, Elena Rybalova, Andrei Bukh +2
We demonstrate that nonlocal coupling enables control of the collective stochastic dynamics in the regime of coherence resonance. The control scheme based on the nonlocal interacti…
Effect of Levy noise on the network of coupled Chialvo neurons: Impact of topology
Swetha P, J. S Ram, D. S. Varghese +9
This research investigates the complex spatiotemporal behaviors of Chialvo neuron maps under the influence of Levy noise on three different network topologies that is a ring networ…
Role of coupling delay in oscillatory activity in autonomous networks of excitable neurons with dissipation
A. V. Bukh, I. A. Shepelev, E. M. Elizarov +3
We study numerically the effects of time delay in networks of delay-coupled excitable FitzHugh Nagumo systems with dissipation. The generation of periodic self-sustained oscillatio…
Delay-induced self-oscillation excitation in the FitzHugh-Nagumo model: regular and chaotic dynamics
Vladimir V. Semenov, Andrei V. Bukh, Nadezhda Semenova
The stochastic FitzHugh-Nagumo model with time delayed-feedback is often studied in excitable regime to demonstrate the time-delayed control of coherence resonance. Here, we show t…
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…
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…
New type of chimera and mutual synchronization of spatiotemporal structures in two coupled ensembles of nonlocally interacting chaotic maps
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…
