Proton pairing in neutron stars

We studied the influence of dispersive self-energy effects, three-body forces, and polarization contributions to the interaction kernel on the {sup 1}S{sub 0} proton pairing in neutron star matter.

Superfluid states of nuclear matter beyond the BCS approximation

The recent progress in the pairing problem and the superfluidity of neutron stars is reviewed. The theory of superfluidity in nuclear and neutron matter is developed beyond the BCS approximation. In

In-medium T matrix for neutron matter

We calculate the equation of state of pure neutron matter, comparing the G-matrix calculation with the in-medium T-matrix result. At low densities, we obtain similar energies per nucleon, however

Screening Effects on $^1S_0$ Pairing in Neutron Matter

The $^1S_0$ superfluidity of neutron matter is studied in the framework of the generalized Gorkov equation. The vertex corrections to the pairing interaction and the self-energy corrections are

Quasiparticle Renormalization and Pairing Correlations in Spherical Superfluid Nuclei

We present a detailed discussion of the solution of Nambu-Gor'kov equations in superfluid nuclei, which provide a consistent framework to deal with the interplay between particle-hole and particle-

Pairing in pure neutron matter

We review the long standing problem of superfluid pairing in pure neutron matter. For the $s$-wave pairing, we summarize the state of the art of many-body approaches including different $nn$



Superfluidity in Neutron Stars

MATTER in the interior of a typical neutron star is a mixture of three degenerate interacting quantum liquids—neutrons, protons and electrons, the latter two having a density at most a few per cent

Theory of superconductivity

A theory of superconductivity is presented, based on the fact that the interaction between electrons resulting from virtual exchange of phonons is attractive when the energy difference between the

3 P 2 − 3 F 2 pairing in neutron matter with modern nucleon-nucleon potentials

We present results for the $^3P_2 - ^3F_2$ pairing gap in neutron matter with several realistic nucleon-nucleon potentials, in particular with recent, phase-shift equivalent potentials. We find that

Theory Of Interacting Fermi Systems

This book provides a detailed exposition of field theoretical methods as applied to zero temperature Fermi liquids. Special attention is paid to the concept of quasiparticles in normal Fermi liquids.
