Effect of non-Gaussian noise sources in a noise-induced transition

Here we study a noise-induced transition when the system is driven by a noise source taken as colored and non-Gaussian. We show-using both, a theoretical approximation and numerical simulations-that there is a shift of the transition as the noise departs from the Gaussian behavior. Also, we confirm the reentrance effect found for colored Gaussian noise and show the behavior of the transition line in the phase-like diagram as the noise departs from Gaussianity in the large correlation time limit.
