摘要：
We present a theory of the thermodynamics of solids which, for the first time, successfully accounts quantitatively for the entire temperature range without perturbation expansion. Quantum effects are absorbed into an effective potential using a variational path-integral method. This potential is used in a classical Monte Carlo calculation.
