Nonequilibrium phase transitions induced by multiplicative noise
We review a mean-field analysis and give the details of a correlation function approach for spatially distributed systems subject to multiplicative noise, white in space and time. We confirm the existence of a pure noise-induced reentrant nonequilibrium phase transition in the model introduced in @C. Van den Broeck et al., Phys. Rev. Lett. 73, 3395 ~1994!#, give an intuitive explanation of its ...

متن کاملNonequilibrium phase transitions induced by multiplicative noise: effects of self-correlation
A recently introduced lattice model, describing an extended system which exhibits a reentrant (symmetry-breaking, second-order) noise-induced nonequilibrium phase transition, is studied under the assumption that the multiplicative noise leading to the transition is colored. Within an effective Markovian approximation and a mean-field scheme it is found that when the self-correlation time tau of...
متن کاملAdditive Noise and Noise-induced Nonequilibrium Phase Transitions
We study how additive noise influences noise-induced nonequilibrium phase transitions. The review of the most recent results and a discussion about open questions is presented. We show that additive noise strongly influences a noise-induced phase transition. We demonstrate also that additive noise can induce such a transition by itself. It can occur both via the excitation of noise-induced osci...
متن کاملPhase transitions induced by noise cross-correlations.
A general approach for treating the spatially extended stochastic systems with the nonlinear damping and correlations between additive and multiplicative noises is developed. Within the modified cumulant expansion method, we derive an effective Fokker-Planck equation with stationary solutions that describe the character of the ordered state. We find that the fluctuation cross-correlations lead ...
