State dependent diffusion in a bistable potential: conditional probabilities and escape rates
Miguel V. Moreno, Daniel G. Barci, Zochil González Arenas
We consider a simple model of a bistable system under the influence of multiplicative noise. We provide a path integral representation of the overdamped Langevin dynamics and compu…

Conditional probabilities in multiplicative noise processes
Miguel V. Moreno, Daniel G. Barci, Zochil González Arenas
We address the calculation of transition probabilities in multiplicative noise stochastic differential equations using a path integral approach. We show the equivalence between the…

Stochastic dynamics of planar magnetic moments in a three-dimensional environment
Zochil González Arenas, Daniel G. Barci, Miguel Vera Moreno
We study the stochastic dynamics of a two-dimensional magnetic moment embedded in a three-dimensional environment, described by means of the stochastic Landau-Lifshitz-Gilbert (sLL…
