Notes on coherent backscattering from a random potential
arXiv:0706.0806 · doi:10.1063/1.2779139
Abstract
We consider the quantum scattering from a random potential of strength $λ^{1/2}$ and with a support on the scale of the mean free path, which is of order $λ^{-1}$. On the basis of maximally crossed diagrams we provide a concise formula for the backscattering rate in terms of the Green's function for the kinetic Boltzmann equation. We briefly discuss the extension to wave scattering.
