Inelastic Multiple Scattering of Interacting Bosons in Weak Random Potentials
arXiv:1203.1722 · doi:10.1103/PhysRevLett.109.030601
Abstract
We develop a diagrammatic scattering theory for interacting bosons in a three-dimensional, weakly disordered potential. We show how collisional energy transfer between the bosons induces the thermalization of the inelastic single-particle current which, after only few collision events, dominates over the elastic contribution described by the Gross-Pitaevskii ansatz.
