摘要：

First and second-order nonequilibrium phase transitions induced by an external nonlinear multiplicative noise are studied. A theoretical approach gives that the physical mechanism responsible for these transitions is a nonlinear instability of the homogeneous phase. Mean-field analysis and numerical simulations confirm the theoretical prediction.
