Journal ArticleDOI
When nonlocal coupling between oscillators becomes stronger: patched synchrony or multichimera states.
TL;DR: It is found that, depending on the coupling strength and range, different multichimera states arise in a transition from classical chimera states, which cannot be observed in simple phase-oscillator models.
Journal ArticleDOI
Chimera states are chaotic transients
TL;DR: The results indicate that chimera states can be considered as chaotic transients, showing the same properties as type-II supertransients in coupled map lattices.
Journal ArticleDOI
Chimera States: The Natural Link Between Coherence and Incoherence
TL;DR: It is shown that in a network of globally coupled oscillators delayed feedback stimulation with realistic stimulation profile generically induces chimera states, which are the natural link between the coherent and the incoherent states.
Journal ArticleDOI
Spectral properties of chimera states.
TL;DR: It is shown that, in this setting, the chimera state is neutrally stable and that the continuous spectrum coincides with the limit of the hyperchaotic Lyapunov spectrum obtained for the finite size systems.
