Abstract

We investigate the effect of microscopic three-body forces on the {sup 3}P F{sub 2} neutron superfluidity in neutron matter, {beta}-stable neutron star matter, and neutron stars by using the BCS theory and the Brueckner-Hartree-Fock approach. We adopt the Argonne V18 potential supplemented with a microscopic three-body force as the realistic nucleon-nucleon interaction. We have concentrated on studying the three-body force effect on the {sup 3}P F{sub 2} neutron pairing gap. It is found that the three-body force effect considerably enhances the {sup 3}P F{sub 2} neutron superfluidity in neutron star matter and neutron stars.

Nucleon Superfluidity in Asymmetric Nuclear Matter and Neutron Star Matter

Journal Article Wei, Zuo; Lombardo, U - AIP Conference Proceedings

We have investigate the nucleon superfluidity in asymmetric nuclear matter and neutron star matter by using the Brueckner-Hartree-Fock approach and the BCS theory. We have predicted the isospin-asymmetry dependence of the nucleon superfluidity in asymmetric nuclear matter and discussed particularly the effect of microscopic three-body forces. It has been shown that the three-body force leads to a strong suppression of the proton {sup 1}S{sub 0} superfluidity in beta-stable neutron star matter. Whereas the microscopic three-body force is found to enhance remarkably the {sup 3}PF{sub 2} neutron superfluidity in neutron star matter and neutron stars.

Neutron superfluidity and the structure of the neutron star inner crust

Journal Article Baldo, M; Tolokonnikov, S - Physics of Atomic Nuclei

A self-consistent quantum approach to describe the inner crust structure of neutron stars is developed within the Wigner-Seitz (WS) approximation, based on the generalized energy functional method involving explicitly neutron and proton pairing correlations. The energy functional is constructed by matching the realistic phenomenological nuclear functional by Fayans et al. for describing the pseudonucleus in the center of the WS cell with the one calculated microscopically for neutron matter within the Brueckner approach with the Argonne v{sub 18} force. The microscopic description of the neutron superfluidity is based on the BCS approach with the same v{sub 18} force. Many-body theorymore »« less

ROLE OF NUCLEONIC FERMI SURFACE DEPLETION IN NEUTRON STAR COOLING

Journal Article Dong, J.; Zuo, W.; Lombardo, U.; ... - Astrophysical Journal

The Fermi surface depletion of beta-stable nuclear matter is calculated to study its effects on several physical properties that determine the neutron star (NS) thermal evolution. The neutron and proton Z factors measuring the corresponding Fermi surface depletions are calculated within the Brueckner–Hartree–Fock approach, employing the AV18 two-body force supplemented by a microscopic three-body force. Neutrino emissivity, heat capacity, and in particular neutron {sup 3}PF{sub 2} superfluidity, turn out to be reduced, especially at high baryonic density, to such an extent that the cooling rates of young NSs are significantly slowed.

Density dependence of the nuclear symmetry energy: A microscopic perspective

Journal Article Vidana, Isaac; Providencia, Constanca; Polls, Artur; ... - Physical Review. C, Nuclear Physics

We perform a systematic analysis of the density dependence of nuclear symmetry energy within the microscopic Brueckner-Hartree-Fock (BHF) approach using the realistic Argonne V18 nucleon-nucleon potential plus a phenomenological three-body force of Urbana type. Our results are compared thoroughly with those arising from several Skyrme and relativistic effective models. The values of the parameters characterizing the BHF equation of state of isospin asymmetric nuclear matter fall within the trends predicted by those models and are compatible with recent constraints coming from heavy ion collisions, giant monopole resonances, or isobaric analog states. In particular we find a value of the slopemore »« less

Nuclear three-body force effect on a kaon condensate in neutron star matter

Journal Article Zuo, W; Li, A; Li, Z; ... - Physical Review. C, Nuclear Physics

We explore the effects of a microscopic nuclear three-body force on the threshold baryon density for kaon condensation in chemical equilibrium neutron star matter and on the composition of the kaon condensed phase in the framework of the Brueckner-Hartree-Fock approach. Our results show that the nuclear three-body force affects strongly the high-density behavior of nuclear symmetry energy and consequently reduces considerably the critical density for kaon condensation provided that the proton strangeness content is not very large. The dependence of the threshold density on the symmetry energy becomes weaker as the proton strangeness content increases. The kaon condensed phase ofmore »« less
