增强耦合相位振荡器复杂网络的同步

Enhancing synchronization in complex networks of coupled phase oscillators

Xingang Wang, Shuguang Guan, Ying-Cheng Lai, Choy Heng Lai

摘要:

通过一个耦合相位振荡器模型,我们分析了如何通过在耦合中引入适当的梯度来增强{ \em非恒等}复杂网络的同步。研究发现,通过在每条链路上指向度大的节点到度小的节点的梯度,增加梯度强度会单调地提前网络同步的{ \em onset},并且在相同梯度强度下,异构网络比同构网络更容易同步.这些发现得到了广泛的模拟验证。

英文摘要:

By a model of coupled phase oscillators, we show analytically how synchronization in {\em non-identical} complex networks can be enhanced by introducing a proper gradient into the couplings. It is found that, by pointing the gradient from the large-degree to the small-degree nodes on each link, increasing the gradient strength will bring forward the {\em onset} of network synchronization monotonically, and, under the same gradient strength, heterogeneous networks are more synchronizable than homogeneous networks. These findings are verified by extensive simulations.
