本文发展了一个三维弱无序势场中相互作用玻色子的图解散射理论。我们展示了玻色子之间的碰撞能量转移如何诱导非弹性单粒子电流的热化，经过几次碰撞事件后，它在Gross-Pitaevskii模型所描述的弹性贡献中占主导地位。
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 a few collision events, dominates over the elastic contribution described by the Gross-Pitaevskii ansatz.
