Abstract

A unification of Brueckner and Jastrow ideas is pursued with the aim of combining the advantages of the hole-line-expansion and variational approaches, while avoiding their disadvantages. The unified theory is achieved by adapting the coupled-cluster or exp(S) formalism to a basis of Jastrow-correlated wave functions. On the one hand, this formulation permits the systematic inclusion of non-Jastrow (particularly, state-dependent) correlations into the description of the ground state. On the other hand, the Jastrow correlations serve to tame the bare interaction to the extent that simple truncations of the new system of coupled-cluster equations may yield reliable results for interesting many-body problems involving realistic interactions and realistic densities. For the case of nuclear matter, a “correlated Bethe-Goldstone equation” is proposed which in effect sums the generalized ladder diagrams of correlated-basis perturbation theory.
