普通噪声是否能诱导混沌系统的完全同步一直是一个具有重要意义和长期争议的话题。我们首先澄清这种现象的机制，并表明，存在一个显着的收缩区域，附近的轨迹收敛，起着决定性的作用。其次，我们证明了，更一般地说，常见的噪声可以诱导相位同步在不同的混沌系统。这种噪声诱导的同步化和同步化跃迁对于理解神经元编码在神经生物学中具有特殊的意义。
Whether common noise can induce complete synchronization in chaotic systems has been a topic of great relevance and long-standing controversy. We first clarify the mechanism of this phenomenon and show that the existence of a significant contraction region, where nearby trajectories converge, plays a decisive role. Second, we demonstrate that, more generally, common noise can induce phase synchronization in nonidentical chaotic systems. Such a noise-induced synchronization and synchronization transitions are of special significance for understanding neuron encoding in neurobiology.
