Langevin simulation of scalar fields: Additive and multiplicative noises and lattice renormalization
(Elsevier B.V., 2012-08-15)
We consider the Langevin lattice dynamics for a spontaneously broken 44 scalar field theory where both additive and multiplicative noise terms are incorporated. The lattice renormalization for the corresponding stochastic ...

Hot Brownian carriers in the Langevin picture: Application to a simple model for the Gunn effect in GaAs
(2013-09-23)
We consider a charged Brownian gas under the influence of external, static and uniform electric and magnetic fields, immersed in a uniform bath temperature. We obtain the solution for the associated Langevin equation, and ...

Non-Markovian expansion in quantum Brownian motion
(2013-10-09)
We consider the non-Markovian Langevin evolution of a dissipative dynamical system in quantum mechanics in the path integral formalism. After discussing the role of the frequency cutoff for the interaction of the system ...
Dynamics of the deconfinement transition
(2007-04-04)
We estimate the dissipation coefficient Γ that appears in Ginzburg-Landau-Langevin equations that describe phenomenologically the deconfinement transition in QCD. This is done through the implementation of Glauber dynamics ...
