具有非线性整体耦合的振子系综中的量子尺寸诱导的同步跃迁

Finite-size-induced transitions to synchrony in oscillator ensembles with nonlinear global coupling

Maxim Komarov, Arkady Pikovsky

摘要:

我们报告有限大小的诱导过渡到同步的人口相振荡器耦合通过一个非线性平均场,这在微观上相当于一个超网络组织的相互作用。使用自洽的方法和直接的数值模拟,我们认为,过渡到同步只发生在有限大小的合奏,并消失在热力学极限。对于所有考虑的设置,其中包括纯粹的确定性振荡器或没有异质性的自然振荡频率,和一个合奏的噪声驱动的相同的振荡器,我们建立比例关系描述的序参量作为一个函数的耦合常数和系统的大小。

英文摘要:

We report on finite-sized-induced transitions to synchrony in a population of phase oscillators coupled via a nonlinear mean field, which microscopically is equivalent to a hypernetwork organization of interactions. Using a self-consistent approach and direct numerical simulations, we argue that a transition to synchrony occurs only for finite-size ensembles, and disappears in the thermodynamic limit. For all considered setups, that include purely deterministic oscillators with or without heterogeneity in natural oscillatory frequencies, and an ensemble of noise-driven identical oscillators, we establish scaling relations describing the order parameter as a function of the coupling constant and the system size.
