摘要：

Using a previously derived general formalism for a dissipative quantum particle in a boson bath, we prove that when the damping is Ohmic, the Kubo-Einstein relation between the diffusion constant and the linear mobility D = kTM holds to all orders in V0 for a periodic potential V(x) = V0 cos(k0x).
