仓本振子网络中的混沌

Chaos in Kuramoto oscillator networks

Christian Bick, Mark J. Panaggio, Erik A. Martens

摘要:

仓本振子被广泛用于解释耦合振荡单元网络中的集体现象。我们证明了两个种群的简单网络与一个通用的耦合方案,其中耦合强度和相位滞后之间和内种群是不同的,可以表现出混沌动力学所描述的奥特和Antonsen [混沌,18,037113(2008)]。这些混乱的平均场动力学普遍出现在整个网络的大小,从连续极限的无限多个振荡器到非常小的网络,每个人口只有两个振荡器。因此,即使在最简单的振荡器网络描述中,也会出现复杂的动力学。

英文摘要:

Kuramoto oscillators are widely used to explain collective phenomena in networks of coupled oscillatory units. We show that simple networks of two populations with a generic coupling scheme, where both coupling strengths and phase lags between and within populations are distinct, can exhibit chaotic dynamics as conjectured by Ott and Antonsen [Chaos, 18, 037113 (2008)]. These chaotic mean-field dynamics arise universally across network size, from the continuum limit of infinitely many oscillators down to very small networks with just two oscillators per population. Hence, complicated dynamics are expected even in the simplest description of oscillator networks.
