振子系综中的两类准周期部分同步

Two types of quasiperiodic partial synchrony in oscillator ensembles

Michael Rosenblum, Arkady Pikovsky

摘要:

我们分析了具有全局非线性耦合的Stuart-Landau振子系综中的准周期部分同步态。我们揭示了两种类型的这样的动态:在第一种情况下,振荡器和平均场的时间平均频率不同,而在第二种情况下,它们是相等的,但振荡器的运动被另外调制。我们描述了从同步状态到两种类型的准周期动力学的过渡,以及两个不同的准周期状态之间的过渡。我们提出了一个例子的分岔图,在那里我们显示了所有这些过渡的边界线,以及域的双稳态。

英文摘要:

We analyze quasiperiodic partially synchronous states in an ensemble of Stuart-Landau oscillators with global nonlinear coupling. We reveal two types of such dynamics: in the first case the time-averaged frequencies of oscillators and of the mean field differ, while in the second case they are equal, but the motion of oscillators is additionally modulated. We describe transitions from the synchronous state to both types of quasiperiodic dynamics, and a transition between two different quasiperiodic states. We present an example of a bifurcation diagram, where we show the borderlines for all these transitions, as well as domain of bistability.
