The Boltzmann--Langevin approach: A simple quantum-mechanical derivation
arXiv:1509.06267 · doi:10.1016/j.physe.2015.08.006
Abstract
We present a simple quantum-mechanical derivation of correlation function of Langevin sources in the semiclassical Boltzmann--Langevin equation. The specific case of electron--phonon scattering is considered. It is shown that the assumption of weak scattering leads to the Poisson nature of the scattering fluxes.
