成簇嵌合体模式形成的对称性破缺机制

Symmetry-breaking mechanism for the formation of cluster chimera patterns

Malbor Asllani, Bram A. Siebert, Alex Arenas, James P. Gleeson

摘要:

集体动力学中秩序的出现是一个迷人的现象,它是许多由耦合实体组成的自然系统的特征。同步是这样一个例子,其中通常由线性或非线性振荡器表示的个体可以在相互作用的配置满足某些条件时自发地相互一致地行动。然而,同步并不总是完美的,相干和非相干振荡器的共存,在文献中被广泛称为嵌合体状态,也是可能的。尽管人们曾多次试图解释嵌合体国家是如何产生的,但它们的出现、稳定性和健壮性仍然是一个长期争论的问题。我们提出了一种方法,旨在建立一个强大的机制,通过该机制嵌合体的起源。我们首先介绍一个稳定性破坏的方法,集群的同步振荡器可以出现。类似地,一个或多个振子簇可能保持不相干,从而产生特定类别的模式,我们在这里将其命名为簇嵌合态。

英文摘要:

The emergence of order in collective dynamics is a fascinating phenomenon that characterizes many natural systems consisting of coupled entities. Synchronization is such an example where individuals, usually represented by either linear or nonlinear oscillators, can spontaneously act coherently with each other when the interactions' configuration fulfills certain conditions. However, synchronization is not always perfect, and the coexistence of coherent and incoherent oscillators, broadly known in the literature as chimera states, is also possible. Although several attempts have been made to explain how chimera states are created, their emergence, stability, and robustness remain a long-debated question. We propose an approach that aims to establish a robust mechanism through which chimeras originate. We first introduce a stability-breaking method where clusters of synchronized oscillators can emerge. Similarly, one or more clusters of oscillators may remain incoherent within yielding a particular class of patterns that we here name cluster chimera states.
