排斥耦合振子的时间自相似同步模式和标度

Temporal self-similar synchronization patterns and scaling in repulsively coupled oscillators

Darka Labavic, Hildegard Meyer-Ortmanns

摘要:

我们研究排斥耦合仓本振子的同步模式,并专注于固有频率的无序的影响。在其他选择中,我们选择网格大小和拓扑结构,只要均匀选择固有频率,我们就可以观察到具有连续吸引子的动态诱导降维。当我们在这些频率中引入无序时,我们发现极限环的周期比单个振荡器的固有频率长几个数量级。此外,我们确定的相位锁定运动,这是自相似的时间和其周期的规模与一个统一的频率分布的逆宽度的权力的临时模式的序列。这种行为为未来的研究提供了挑战。

英文摘要:

We study synchronization patterns in repulsively coupled Kuramoto oscillators and focus on the impact of disorder in the natural frequencies. Among other choices we select the grid size and topology in a way that we observe a dynamically induced dimensional reduction with a continuum of attractors as long as the natural frequencies are uniformly chosen. When we introduce disorder in these frequencies, we find limit cycles with periods that are orders of magnitude longer than the natural frequencies of individual oscillators. Moreover we identify sequences of temporary patterns of phase-locked motion, which are self-similar in time and whose periods scale with a power of the inverse width about a uniform frequency distribution. This behavior provides challenges for future research.
