标题： The Origin of Non-chaotic Behavior in Identically Driven Systems

摘要： 最近发现，由相同随机噪声驱动的不同物理系统在长时间后表现出完全相同的特性。还有一种观点认为，这是数值实验有限精度的结果。 在这里，我们表明非混沌行为的根源在于这些系统的吸引子的结构不稳定性，当驱动力足够强时，吸引子会变为一个稳定的不动点。 我们发现这在文献中研究的所有系统中都成立。 因此，我们确认，在混沌系统中，除非噪声破坏了奇怪吸引子并且系统不再具有混沌性，否则通过增加噪声无法实现同步。 显示英文摘要

摘要： Recently it has been found that different physical systems driven by identical random noise behave exactly identical after a long time. It is also suggested that this is an outcome of finite precision in numerical experiments. Here we show that the origin of the non-chaotic behavior lies in the structural instability of the attractor of these systems which changes to a stable fixed point for strong enough drive. We see this to be true in all the systems studied in literature. Thus we affirm that in chaotic systems, synchronization can not occur only by addition of noise unless the noise destroys the strange attractor and the system is no longer chaotic.
