Synchronization and chimera are examples of collective behavior observed in an ensemble of coupled nonlinear oscillators. Recent studies have focused on their discovery in systems with least possible number of oscillators. Here we present an experimental study revealing the synchronization route to weak chimera via quenching, clustering, and chimera states in a single system of four coupled candle-flame oscillators. We further report the discovery of multiphase weak chimera along with experimental evidence of the theoretically predicted states of in-phase chimera and antiphase chimera.
同步和嵌合体是在耦合非线性振荡器集合中观察到的集体行为的例子。最近的研究集中在具有尽可能少的振荡器数量的系统中发现它们。在这里,我们通过熄灭、聚类和单个四耦合蜡烛火焰振荡器系统中的嵌合体状态,展示了一个实验研究,揭示了从同步到弱嵌合体的途径。我们还报告了多相弱嵌合体的发现以及同相嵌合体和反相嵌合体的理论预测状态的实验证据。
