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…
Chimera states in population dynamics: networks with fragmented and hierarchical connectivities
Johanne Hizanidis, Evangelia Panagakou, Iryna Omelchenko +3
We study numerically the development of chimera states in networks of nonlocally coupled oscillators whose limit cycles emerge from a Hopf bifurcation. This dynamical system is ins…
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…
