Nonequilibrium phase transitions induced by multiplicative noise: effects of self-correlation
S. E. Mangioni, R. R. Deza, R. Toral +1
A recently introduced lattice model, describing an extended system which exhibits a reentrant (symmetry-breaking, second-order) noise-induced nonequilibrium phase transition, is st…

Disordering effects of color in nonequilibrium phase transitions induced by multiplicative noise
S. Mangioni, R. Deza, H. S. Wio +1
The model introduced by Van den Broeck, Parrondo and Toral [Phys. Rev. Lett.73, 3395 (1994)] -- leading to a second-order-like noise-induced nonequilibrium phase transition which s…
