The self-consistent harmonic theory developed in the preceding paper for the study of classical solvation dynamics in glassy media is extended to treat quantum solvation. In particular, a quantum set of optimized normal modes and a methodology for calculating, quantum mechanically, all multiphonon contributions to solvation are presented. The simulation of solvation dynamics in a low temperature glass shows nontrivial quantum effects. The relationship between the quantum theory presented in this work and previous theories is discussed.

One may envision that a path integral calculation can also reduce the problem to that of simple matrix operations. Some formal difficulties may exist in this approach, however, due to the coupling of positions and momenta.
