A Tweezer for Chimeras in Small Networks
Iryna Omelchenko, Oleh E. Omel'chenko, Anna Zakharova +2
We propose a control scheme which can stabilize and fix the position of chimera states in small networks. Chimeras consist of coexisting domains of spatially coherent and incoheren…
Delayed-feedback chimera states: Forced multiclusters and stochastic resonance
Vladimir Semenov, Anna Zakharova, Yuri Maistrenko +1
A nonlinear oscillator model with negative time-delayed feedback is studied numeri- cally under external deterministic and stochastic forcing. It is found that in the unforced syst…
Hyperbolicity impedes emergence of chimera states in networks of nonlocally coupled chaotic oscillators
Nadezhda Semenova, Anna Zakharova, Eckehard Schöll +1
We analyze nonlocally coupled networks of identical chaotic oscillators with either time-discrete or time-continuous dynamics (Henon map, Lozi map, Lorenz system). We hypothesize t…
Chimera patterns under the impact of noise
Sarah A. M. Loos, Jens Christian Claussen, Eckehard Schöll +1
We investigate two types of chimera states, i.e., patterns consisting of coexisting spatially separated domains with coherent and incoherent dynamics, in ring networks of Stuart-La…
Stable and transient multi-cluster oscillation death in nonlocally coupled networks
Isabelle Schneider, Marie Kapeller, Sarah Loos +3
In a network of nonlocally coupled Stuart-Landau oscillators with symmetry-breaking coupling, we study numerically, and explain analytically, a family of inhomogeneous steady state…
Quantum signatures of Chimera states
V. M. Bastidas, I. Omelchenko, A. Zakharova +2
Chimera states are complex spatiotemporal patterns in networks of identical oscillators, characterized by the coexistence of synchronized and desynchronized dynamics. Here we propo…
Amplitude chimeras and chimera death in dynamical networks
Anna Zakharova, Marie Kapeller, Eckehard Schöll
We find chimera states with respect to amplitude dynamics in a network of Stuart-Landau oscillators. These partially coherent and partially incoherent spatio-temporal patterns appe…
Nonlinearity of local dynamics promotes multi-chimeras
Iryna Omelchenko, Anna Zakharova, Philipp Hoevel +2
Chimera states are complex spatio-temporal patterns in which domains of synchronous and asynchronous dynamics coexist in coupled systems of oscillators. We examine how the characte…
