无标度网络中向振幅死亡的转变

Transition to amplitude death in scale-free networks

Weiqing Liu, Xingang Wang, Shuguang Guan, Choy Heng Lai

摘要:

研究了非线性振子无标度网络中的振幅死亡现象。随着耦合强度的增加,网络将经历三个阶段接近完全幅值死亡状态。第一阶段的特征是节点振幅的\emph{"stair-like"}分布,过渡是由振幅阶梯的\emph{hierarchical death}完成的。第二阶段和第三阶段的特征分别在于同步集群的持续消除和非同步节点的快速死亡。

英文摘要:

Transition to amplitude death in scale-free networks of nonlinear oscillators is investigated. As the coupling strength increases, the network will undergo three stages in approaching to the state of complete amplitude death. The first stage is featured by a \emph{"stair-like"} distribution of the node amplitude, and the transition is accomplished by a \emph{hierarchical death} of the amplitude stairs. The second and third stages are characterized by, respectively, a continuing elimination of the synchronous clusters and a fast death of the non-synchronized nodes.
