FISCALETTI, D.. Brownian motion and polarized three-dimensional quantum vacuum. Rev. mex. fis. [online]. 2021, vol.67, n.4, e040706.  Epub 14-Mar-2022. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.67.040706.

A nonlinear model of Brownian motion is developed in a three-dimensional quantum vacuum defined by a variable quantum vacuum energy density corresponding to processes of creation/annihilation of virtual particles. In this model, the polarization of the quantum vacuum determined by a perturbative fluctuation of the quantum vacuum energy density associated with a fluctuating viscosity, which mimics the action of dark matter, emerges as the fundamental entity which generates the Brownian motion.

Palavras-chave : Brownian motion; three-dimensional quantum vacuum; variable quantum vacuum energy density; perturbative fluctuation of the quantum vacuum energy density.
