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 paper, the quantum fluctuations of the two-phase Skyrme soliton model of the nucleon were formulated and the p-wave π N phase shift and the Roper to π n decay width were calculated as a function of the equlibrium defect radius R 0.

TL;DR: In this paper, a review of perturbative many-body descriptions of several nuclear systems is presented, including symmetric and asymmetric nuclear matter and finite nuclei with few valence particles.
445 citations
TL;DR: In this paper, various approaches to account for such correlations are described and compared to each other, including the holeline expansion, the coupled cluster or exponential S approach, the selfconsistent evaluation of Greens functions, variational approaches using correlated basis functions and recent developments employing quantum Monte-Carlo techniques.

TL;DR: In this paper, the chiral bag model for the nucleon at low energy was reviewed and a reasonably good description was given for nucleon in both cases at an intermediate bag radius R ~ 0.6 fm.

TL;DR: In this paper, a self-consistent Green function approach for the many-body theory of interacting fermions is presented and its application to nuclear systems is presented. But the authors focus on the consistent inclusion of short-range and long-range correlations induced by realistic nucleon-nucleon interactions.
Abstract: Recent developments in the many-body theory of interacting fermions are discussed employing a self-consistent Green function approach. This scheme is outlined and its application to nuclear systems is presented. Special attention is paid to the consistent inclusion of short-range and long-range correlations induced by realistic nucleon-nucleon interactions. Such correlations lead to occupation probabilities which deviate from the simple mean-field or shell-model description. The scheme is extended to incorporate relativistic effects. Also applications of field theoretical models for hadrons in a nuclear medium and their relation to QCD are discussed.

TL;DR: In this article, a survey of simple pairing properties for the Reid potential is made and it is suggested that the actual ground state of nuclear matter around the empirical saturation density corresponds to a superfluid with pairing occurring with deuteron quantum numbers.
