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.

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, 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.

TL;DR: Hard (infinitely hard) and soft (Yukawa) core potentials have been fit to Yale and Livermore phase parameters and low-energy data as discussed by the authors, and it is found that neither the short-range behavior of the potentials nor the central-to-tensor ratio in the 3 S 1 - 3 D 1 state is well determined by the data.

TL;DR: In this paper, a variational treatment based on wave functions was applied to the problem of the $N$-particle system with strong interactions, and the expectation values, which cannot be factored into singleparticle integrals, were evaluated by a cluster development in powers of the particle density.
Abstract: A trial solution constructed from two-particle functions is applied to the problem of the $N$-particle system with strong interactions. In a variational treatment based on this wave function the expectation values, which cannot be factored into single-particle integrals, are evaluated by a cluster development in powers of the particle density. The procedure is illustrated by a calculation of the pair distribution function and zero-point energy of the hard sphere gas, for Bose and Fermi statistics.
