Control of chimeras in small networks — Iryna Omelchenko1, Oleh Omel’chenko2, Anna Zakharova1, Matthias Wolfrum2, and •Eckehard Schöll1 — 1Institut für Theoretische Physik, Technische Universität Berlin, Hardenbergstraße 36, 10623 Berlin, Germany — 2Weierstrass Institute, Mohrenstraße 39, 10117 Berlin, Germany
We propose a control scheme which can stabilize and fix the position of chimera states in small networks [1]. Chimeras consist of coexisting domains of spatially coherent and incoherent dynamics in systems of nonlocally coupled identical oscillators. Chimera states are generally difficult to observe in small networks due to their short lifetime and erratic drifting of the spatial position of the incoherent domain. The control scheme, like a tweezer, might be useful in experiments, where usually only small networks can be realized.
