研究了振子网络中在完全同步态和部分同步态之间产生双稳的对称性破缺机制。结果表明，在弱全局耦合的情况下，具有单峰频率分布和不同幅度的两组振子可简化为非对称耦合的模块化网络。随着耦合强度的增加，观察到一个孤立的完全同步态的同步转变。结果在热力学极限下得到了理论解释，并在化学振荡器实验中得到了证实。
A symmetry-breaking mechanism is investigated that creates bistability between fully and partially synchronized states in oscillator networks. Two populations of oscillators with unimodal frequency distribution and different amplitudes, in the presence of weak global coupling, are shown to simplify to a modular network with asymmetrical coupling. With increasing the coupling strength, a synchronization transition is observed with an isolated fully synchronized state. The results are interpreted theoretically in the thermodynamic limit and confirmed in experiments with chemical oscillators.
