First Passage Time Statistics For Systems Driven by Long Range Gaussian Noises
Aldo H. Romero, J. M. Sancho, Katja Lindenberg
We examine the mean first passage time for a particle driven by highly correlated Gaussian fluctuations to reach one or more predetermined boundaries. We discuss a numerical algori…

An entropy-driven noise-induced phase transition
M. Ibanes, J. Garcia-Ojalvo, R. Toral +1
We introduce a class of exactly solvable models which exhibit an ordering noise-induced phase transition driven by an entropic mechanism. In contrast with previous studies, order d…

Dynamic Renormalization Group Study of the Model with Colored Noise
J. Garcia-Ojalvo, J. M. Sancho, H. Guo
The non-conserved model defined by a Langevin equation with external non-white noise is studied by means of the Dynamic Renormalization Group. The correlation time of the noi…
