NEW DERIVATION OF A THEORY OF QUANTUM CRYSTALS.
Abstract
A new variational-cluster expansion derivation of Guyer's theory of the ground-state of a quantum crystal is presented. The results are identical with his in the two-body correlation approximation except that the variational approach provides a justification of the minimization technique used to choose the unperturbed Hamiltonian. The treatments differ in the higher correlation terms because of the use of a Jastrow trial function. (Author)
