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 کاملChimera States in populations of nonlocally coupled chemical oscillators.
Chimera states occur spontaneously in populations of coupled photosensitive chemical oscillators. Experiments and simulations are carried out on nonlocally coupled oscillators, with the coupling strength decreasing exponentially with distance. Chimera states with synchronized oscillators, phase waves, and phase clusters coexisting with unsynchronized oscillators are analyzed. Irregular motion o...
متن کاملMulticluster and traveling chimera states in nonlocal phase-coupled oscillators.
Chimera states consisting of domains of coherently and incoherently oscillating identical oscillators with nonlocal coupling are studied. These states usually coexist with the fully synchronized state and have a small basin of attraction. We propose a nonlocal phase-coupled model in which chimera states develop from random initial conditions. Several classes of chimera states have been found: (...
متن کاملPersistent chimera states in nonlocally coupled phase oscillators.
Chimera states in the systems of nonlocally coupled phase oscillators are considered stable in the continuous limit of spatially distributed oscillators. However, it is reported that in the numerical simulations without taking such limit, chimera states are chaotic transient and finally collapse into the completely synchronous solution. In this Rapid Communication, we numerically study chimera ...
