A nonperturbative microscopic theory of Hamiltonian lattice gauge systems
arXiv:cond-mat/9411012
Abstract
A review is given of our recent application of a systematic microscopic formulation of quantum many-body theory, namely the coupled-cluster method (CCM), to Hamiltonian lattice gauge models in the pure gauge sector. It is emphasized that our CCM results represent a natural extension or resummation of the results from the strong-coupling perturbation theory.
