Chimera states for coupled oscillators.
Arrays of identical oscillators can display a remarkable spatiotemporal pattern in which phase-locked oscillators coexist with drifting ones. Discovered two years ago, such "chimera states" are believed to be impossible for locally or globally coupled systems; they are peculiar to the intermediate case of nonlocal coupling. Here we present an exact solution for this state, for a ring of phase o...
متن کاملChimera States in a Ring of Nonlocally Coupled oscillators
Daniel M. Abrams and Steven H. Strogatz Niels Bohr Institute, Blegdamsvej 17, 2100 Copenhagen Ø, Denmark Abstract Arrays of identical limit-cycle oscillators have been used to model a wide variety of patternforming systems, such as neural networks, convecting fluids, laser arrays, and coupled biochemical oscillators. These systems are known to exhibit rich collective behavior, from synchrony an...
متن کاملImperfect chimera states for coupled pendula
The phenomenon of chimera states in the systems of coupled, identical oscillators has attracted a great deal of recent theoretical and experimental interest. In such a state, different groups of oscillators can exhibit coexisting synchronous and incoherent behaviors despite homogeneous coupling. Here, considering the coupled pendula, we find another pattern, the so-called imperfect chimera stat...
متن کاملChimera states in a multilayer network of coupled and uncoupled neurons.
We study the emergence of chimera states in a multilayer neuronal network, where one layer is composed of coupled and the other layer of uncoupled neurons. Through the multilayer structure, the layer with coupled neurons acts as the medium by means of which neurons in the uncoupled layer share information in spite of the absence of physical connections among them. Neurons in the coupled layer a...
متن کاملExperimental observation of chimera and cluster states in a minimal globally coupled network.
A "chimera state" is a dynamical pattern that occurs in a network of coupled identical oscillators when the symmetry of the oscillator population is broken into synchronous and asynchronous parts. We report the experimental observation of chimera and cluster states in a network of four globally coupled chaotic opto-electronic oscillators. This is the minimal network that can support chimera sta...
