摘要:

近年来,爆炸相变,如爆炸渗流、爆炸同步等引起了人们广泛的研究兴趣。到目前为止,大多数现有的作品研究Kuramoto型模型,其中只涉及相变量。在这里,我们报告的发生爆炸振荡淬火耦合斯图尔特-朗道振荡器,结合相位和振幅动态系统。我们观察到三种具有不同微观发生机制的典型情景,即,普通振荡死亡、层次振荡死亡和簇爆发振荡死亡,分别对应不同频率分布的振子。我们进行了理论分析,并获得后向转变点,这是独立的具体的频率分布。数值结果与理论预测一致。

英文摘要:

Recently, the explosive phase transitions, such as explosive percolation and explosive synchronization, have attracted extensive research interest. So far, most existing works investigate Kuramoto-type models, where only phase variables are involved. Here, we report the occurrence of explosive oscillation quenching in a system of coupled Stuart-Landau oscillators that incorporates both phase and amplitude dynamics. We observe three typical scenarios with distinct microscopic mechanism of occurrence, i.e., ordinary, hierarchical, and cluster explosive oscillation death, corresponding to different frequency distributions of oscillators, respectively. We carry out theoretical analyses and obtain the backward transition point, which is shown to be independent of the specific frequency distributions. Numerical results are consistent with the theoretical prediction.
