Chimera states for directed networks [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2021 We demonstrate that chimera behavior can be observed in ensembles of phase oscillators with unidirectional coupling. For a small network consisting of only three identical oscillators (cyclic triple), tiny chimera islands arise in the parameter space.

Embedded chimera states in recurrent neural networks
Communications Physics, 2022 Chimera states provide an intriguing physical platform to explore synchronization effects in neural networks and brain activity. Here, a recurrent neural network with embedded Chimera states is demonstrated, suggesting the generality and robustness of ...

Chimera states induced by spike timing-dependent plasticity in a regular neuronal network
AIP Advances, 2022 Chimera states are spatiotemporal patterns in which distinct dynamics coexist, such as synchronous and asynchronous patterns. In this work, we study the effect of spike timing-dependent plasticity (STDP) on the emergence of chimera states.

Machine Learning Assisted Chimera and Solitary States in Networks
Frontiers in Physics, 2021 Chimera and Solitary states have captivated scientists and engineers due to their peculiar dynamical states corresponding to co-existence of coherent and incoherent dynamical evolution in coupled units in various natural and artificial systems.

Two-frequency chimera state in a ring of nonlocally coupled Brusselators. [PDF]
PLoS ONE, 2017 Chimera states, which consist of coexisting domains of spatially coherent and incoherent dynamics, have been intensively investigated in the past decade.

Amplitude-mediated chimera states [PDF]
Physical Review E, 2013 We investigate the possibility of obtaining chimera state solutions of the non-local Complex Ginzburg-Landau Equation (NLCGLE) in the strong coupling limit when it is important to retain amplitude variations. Our numerical studies reveal the existence of a variety of amplitude mediated chimera states (including stationary and non-stationary two cluster

Susceptibility of transient chimera states [PDF]
Physical Review E, 2020 Chaotic dynamics of a dynamical system is not necessarily persistent. If there is (without any active intervention from outside) a transition towards a (possibly nonchaotic) attractor, this phenomenon is called transient chaos, which can be observed in a variety of systems, e.g., in chemical reactions, population dynamics, neuronal activity, or cardiac

Autowave structures in two-dimensional lattices of nonlocally coupled oscillators [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамика, 2020 Objective. The aim of the research was to compare the dynamics of spiral and target structures including the dynamics of chimera states in ensembles with different nodes. Numeric simulations for autowave structures in two-dimensional ensembles of coupled

Chimera States in Star Networks [PDF]
International Journal of Bifurcation and Chaos, 2016 We consider star networks of chaotic oscillators, with all end-nodes connected only to the central hub node, under diffusive coupling, conjugate coupling and mean-field diffusive coupling. We observe the existence of chimeras in the end-nodes, which are identical in terms of the coupling environment and dynamical equations. Namely, the symmetry of the
