论文摘要
我们通过引入相位滞后全偶联的三个相同的机械振荡器（MetRonomes）的最小网络中获得实验性嵌合体状态。为此，我们开发了一种实时模型偶联机制，该机制允许耦合拓扑，强度和相位延伸的灵活和在线变化。嵌合体状态表明自己是两个同步和一个异步振荡器之间平均频率的不匹配。我们发现这种引人注目的嵌合行为在广泛的参数区域中是鲁棒的。然而，在其他参数下，嵌合体状态可能会失去稳定性，系统行为表现为在三个鞍型嵌合体之间的异斜斜切换。我们的实验观察与模型模拟有定性协议。
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.
