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…
Path Integral approach to nonequilibrium potentials in multiplicative Langevin dynamics
Daniel G. Barci, Zochil González Arenas, Miguel Vera Moreno
We present a path integral formalism to compute potentials for nonequilibrium steady states, reached by a multiplicative stochastic dynamics. We develop a weak-noise expansion, whi…
Langevin dynamics for vector variables driven by multiplicative white noise: a functional formalism
Miguel Vera Moreno, Zochil González Arenas, Daniel G. Barci
We discuss general multi-dimensional stochastic processes driven by a system of Langevin equations with multiplicative white noise. In particular, we address the problem of how tim…
