具有相互作用时滞和高阶相互作用的耦合振子种群的分层同步

Tiered synchronization in coupled oscillator populations with interaction delays and higher-order interactions

Per Sebastian Skardal, Can Xu

摘要:

研究了具有时滞和高阶相互作用的耦合相位振子的大种群同步问题。随着这些效应中的每一个单独地通过同步开始时的亚临界性和鞍节点的发展引起不相干和同步之间的双稳态,我们发现它们的组合产生了双稳态背后的另一种机制,其中开始时的超临界性可以保持,而两个鞍节点的形成产生了分层同步,即,在弱同步状态和强同步状态之间的双稳性。我们证明了这些发现,首先推导出系统的低维动力学,并使用稳定性和稳态分析检查系统分叉。

英文摘要:

We study synchronization in large populations of coupled phase oscillators with time-delays, higher order interactions. With each of these effects individually giving rise to bistabiltiy between incoherence and synchronization via a subcriticality at the onset of synchronization and the development of a saddle node, we find that their combination yields another mechanism behind bistability, where supercriticality at onset may be maintained and instead the formation of two saddle nodes creates tiered synchronization, i.e., bistability between a weakly synchronized state and a strongly synchronized state. We demonstrate these findings by first deriving the low dimensional dynamics of the system and examining the system bifurcations using a stability and steady-state analysis.
