具有双峰频率分布的Kuramoto模型中滞后的存在性

Existence of hysteresis in the Kuramoto model with bimodal frequency distributions

Diego Pazó, Ernest Montbrió

摘要:

我们研究了具有双模态固有频率分布的仓本模型的同步过渡。先前的研究已经得出结论,如果双峰分布接近单峰分布,由于中心凹陷的浅,该模型表现出滞后相变。在这里,我们表明,接近单峰双峰边界并不一定意味着滞后时的宽度,但不是深度,中央倾角趋于零。我们得出这一结论,从一个合适的家庭的双峰分布的仓本模型的详细研究。

英文摘要:

We investigate the transition to synchronization in the Kuramoto model with bimodal distributions of the natural frequencies. Previous studies have concluded that the model exhibits a hysteretic phase transition if the bimodal distribution is close to a unimodal one, due to the shallowness the central dip. Here we show that proximity to the unimodal-bimodal border does not necessarily imply hysteresis when the width, but not the depth, of the central dip tends to zero. We draw this conclusion from a detailed study of the Kuramoto model with a suitable family of bimodal distributions.
