A covariant fermionic path integral for scalar Langevin processes with multiplicative white noise
Daniel G. Barci, Leticia F. Cugliandolo, Zochil González Arenas
We revisit the construction of the fermionic path-integral representation of overdamped scalar Langevin processes with multiplicative white noise, focusing on the covariance of the…
Identifying phase transitions in physical systems with neural networks: a neural architecture search perspective
Rodrigo Carmo Terin, Zochil González Arenas, Roberto Santana
The use of machine learning algorithms to investigate phase transitions in physical systems is a valuable way to better understand the characteristics of these systems. Neural netw…
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…
An estimation of distribution algorithm for the computation of innovation estimators of diffusion processes
Zochil González Arenas, Juan Carlos Jimenez, Li-Vang Lozada-Chang +1
Estimation of Distribution Algorithms (EDAs) and Innovation Method are recognized methods for solving global optimization problems and for the estimation of parameters in diffusion…
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…
