摘要:

通过引入相位滞后的全对全耦合,我们在三个相同的机械振荡器(节拍器)的最小网络中获得了实验嵌合态。为此,我们开发了一种实时模型在环耦合机制,允许灵活和在线改变耦合拓扑结构,强度和相位滞后。嵌合态表现为两个同步振荡器和一个去同步振荡器之间的平均频率失配。我们发现这种惊人的嵌合行为是强大的在一个广泛的参数区域。然而,在其他参数下,嵌合体状态可能会失去稳定性,系统行为表现为三个鞍型嵌合体之间的异宿切换。我们的实验观察与模型模拟定性一致。

英文摘要:

We obtain experimental chimera states in the minimal network of three identical mechanical oscillators (metronomes), by introducing phase-lagged all-to-all coupling. For this, we have developed a real-time model-in-the-loop coupling mechanism that allows for flexible and online change of coupling topology, strength and phase-lag. The chimera states manifest themselves as a mismatch of average frequency between two synchronous and one desynchronized oscillator. We find this kind of striking chimeric behavior is robust in a wide parameter region. At other parameters, however, chimera state can lose stability and the system behavior manifests itself as a heteroclinic switching between three saddle-type chimeras. Our experimental observations are in a qualitative agreement with the model simulation.
