摘要：

We develop an inverse friction expansion for the diffusion of particles in an inhomogeneous medium based on the Mori formalism starting from a microscopic Hamiltonian. The friction is related to the vibrational correlation function of the substrate. An analytic formula is obtained for the diffusion constant in the high-friction limit. © 1990 The American Physical Society.
