度-频相关性对网络同步的影响:普适性和全锁相

Effects of degree-frequency correlations on network synchronization: universality and full phase-locking

Per Sebastian Skardal, Jie Sun, Dane Taylor, Juan G. Restrepo

摘要:

我们引入一个模型来研究度-频率相关性对耦合振子网络同步的影响。分析这个模型,我们发现几个显著的特点。我们发现一个静止的同步状态是(i)普遍的,即,由全局序参量测量的同步程度与网络拓扑无关,以及(i i)完全锁相,即,尽管具有不同的固有频率,所有振荡器都同时锁相。这种状态将另外两类相关性的不同行为定性地分开,在这两类相关性中,慢振荡器和快振荡器可以分别保持不同步。我们关闭的动力学分析下任意度的频率相关性。

英文摘要:

We introduce a model to study the effect of degree-frequency correlations on synchronization in networks of coupled oscillators. Analyzing this model, we find several remarkable characteristics. We find a stationary synchronized state that is (i) universal, i.e., the degree of synchrony, as measured by a global order parameter, is independent of network topology, and (ii) fully phase-locked, i.e., all oscillators become simultaneously phase-locked despite having different natural frequencies. This state separates qualitatively different behaviors for two other classes of correlations where, respectively, slow and fast oscillators can remain unsynchronized. We close by presenting analysis of the dynamics under arbitrary degree-frequency correlations.
