有限N Kuramoto模型的完全同步解和同步相变

Fully Synchronous Solutions and the Synchronization Phase Transition for the Finite N Kuramoto Model

Jared C. Bronski, Lee DeVille, Moon Jip Park

摘要:

我们提出了一个详细的分析同步解决方案的稳定性仓本系统的振荡器。我们导出了一个解析表达式,计算与给定的定态解相关联的非稳定流形的维数。从这一点,我们能够得到一些后果,包括:分析表达式的第一个和最后一个频率向量同步,上界和下界的概率,随机选择的频率向量将同步,并非常尖锐的结果上的大$N$限制这个模型。在此计算中的一个惊喜是,对于高斯分布的频率,完全同步的正确缩放不是一个通常在文献中研究-而是,有一个对数校正的缩放,这是相关的极值统计的随机频率向量。

英文摘要:

We present a detailed analysis of the stability of synchronized solutions to the Kuramoto system of oscillators. We derive an analytical expression counting the dimension of the unstable manifold associated to a given stationary solution. From this we are able to derive a number of consequences, including: analytic expressions for the first and last frequency vectors to synchronize, upper and lower bounds on the probability that a randomly chosen frequency vector will synchronize, and very sharp results on the large $N$ limit of this model. One of the surprises in this calculation is that for frequencies that are Gaussian distributed the correct scaling for full synchrony is not the one commonly studied in the literature---rather, there is a logarithmic correction to the scaling which is related to the extremal value statistics of the random frequency vector.
