嵌合体死亡:动态网络中的对称性破缺

Chimera Death: Symmetry Breaking in Dynamical Networks

Anna Zakharova, Marie Kapeller, Eckehard Schöll

摘要:

对于具有非局域拓扑结构和破环耦合的一般振荡器网络,我们建立了新的部分相干非均匀空间模式,它结合了嵌合体状态(共存的不一致的相干和非相干域)和振荡死亡(振荡抑制)的特征,我们称之为嵌合体死亡。我们表明,由于非定域性的相互作用和耦合导致的旋转对称性破坏,从振荡行为到稳态状态的两种不同情况是可能的:通过同相同步振荡从振幅嵌合体到嵌合体死亡的转变,以及直接突变较大耦合强度的转变。

英文摘要:

For a network of generic oscillators with nonlocal topology and symmetry-breaking coupling we establish novel partially coherent inhomogeneous spatial patterns, which combine the features of chimera states (coexisting incongruous coherent and incoherent domains) and oscillation death (oscillation suppression), which we call chimera death. We show that due to the interplay of nonlocality and breaking of rotational symmetry by the coupling two distinct scenarios from oscillatory behavior to a stationary state regime are possible: a transition from an amplitude chimera to chimera death via in-phase synchronized oscillations, and a direct abrupt transition for larger coupling strength.
