TL;DR: In this article, a ring diagram model-space nuclear matter theory is formulated and applied to the calculation of the binding energy per nucleon (BE A ), saturation Fermi momentum (kF) and incompressibility coefficient (K) of symmetric nuclear matter, using the Paris and Reid nucleon-nucleon potentials.

TL;DR: In this article, the particle-particle (pp) and particle-hole (ph) ring diagrams in the linked diagram expansion of the ground-state energy shift Δ E 0 for many-body systems are derived, given as an integral involving G pp ( ω, λ ) ν, where G pp is the pp Green function, υ the interaction hamiltonian (taken to be two-body) and λ a strength parameter to be integrated over from 0 to 1.

TL;DR: In this paper, a general method for determining the normalization of the RPA type of wave functions from the respective RPA vertex functions is proposed, and the implications of the present theory on quenchings of nuclear electromagnetic transitions are discussed.

TL;DR: In this paper, a model space P and a corresponding finite temperature reaction matrix K are introduced in order to take care of the strong short-range correlations between nucleons, and the contribution from the particle-particle (hole-hole) ring diagrams to the thermodynamic potential Ω is given in terms of simple integrals of the form ∝ 0 1 d λ tr p { M ( λ ) K } where λ is a strength parameter, and M a thermal transition matrix which is calculated from a finite-temperature RPA-type secular equation.
