我们报告一个简单的模型的空间分布的系统，受乘性噪声，白色在空间和时间，可以进行非平衡相变到一个破胶态，而没有这样的过渡存在的情况下的噪声项。该过渡具有类似于在二阶平衡相变观察到的功能：发散的相关长度和敏感性，临界慢化，和标度特性。此外，过渡被发现是可重入的：有序状态出现在噪声强度的临界值，但再次消失在一个更高的值的噪声强度。
We report on a simple model of a spatially distributed system which, subject to multiplicative noise, white in space and time, can undergo a nonequilibrium phase transition to a symmetry-breaking state, while no such transition exists in the absence of the noise term. The transition possesses features similar to those observed at second order equilibrium phase transitions: divergence of the correlation length and of the susceptibility, critical slowing down, and scaling properties. Furthermore, the transition is found to be reentrant: The ordered state appears at a critical value of the noise intensity but disappears again at a higher value of the noise strength.
