چکیده

We investigate dense matter in the context of Sakai and Sugimoto’s holographic model of QCD at zero temperature but finite baryon density in the Wigner-Seitz approximation. In bulk, baryons are treated as instantons on S3×R1 in each Wigner-Seitz cell. At low density, the energy density varies as n 1/3 B while at high density it varies as n 5/3 B . In holographic QCD Skyrmions are instanton holonomies along the conformal direction. The high density phase is identified with a crystal of holographic Skyrmions with restored chiral symmetry at about 4M3 KK/π 5.

Chiral quark-soliton model in the Wigner-Seitz approximation

In this paper we study the modification of the properties of the nucleon in the nucleus within the quark-soliton model. This is a covariant, dynamical model, which provides a non–linear representation of the spontaneously broken SU(2)L × SU(2)R symmetry of QCD. The effects of the nuclear medium are accounted for by using the Wigner-Seitz approximation and therefore reducing the complex many-bod...

Neutron Star Crust beyond the Wigner-seitz Approximation

For more than three decades, the inner crust of neutron stars, formed of a solid lattice of nuclear clusters coexisting with a gas of electrons and neutrons, has been traditionally studied in the Wigner-Seitz approximation. The validity of this approximation is discussed in the general framework of the band theory of solids, which has been recently applied to the nuclear context. Using this nov...

A Model of Dense-plasma Atomic Structure for Equation-of-state Calculations

A model of dense plasmas relying on the superconfiguration approximation is presented. In each superconfiguration the nucleus is totally screened by the electrons in a Wigner-Seitz sphere (ion-sphere model). Superconfigurations of the same charge are grouped into ions. It is shown that boundary values of the wavefunctions play a crucial role in the form of the Virial theorem from which the pres...

Baryonic Response of Dense Holographic QCD

The response function of a homogeneous and dense hadronic system to a timedependent (baryon) vector potential is discussed for holographic dense QCD (D4/D8 embedding) both in the confined and deconfined phases. Confined holographic QCD is an uncompressible and static baryonic insulator at large Nc and large λ, with a gapped vector spectrum and a massless pion. Deconfined holographic QCD is a di...

applied to the neutron star

The role of the boundary conditions in the Wigner-Seitz approximation applied to the neutron star inner crust. Abstract The influence of the boundary conditions used in the Wigner-Seitz approximation applied to the neutron star inner crust is examined. The generalized energy functional method which includes neutron and proton pairing correlations is used. Predictions of two versions of the boun...
