Nuclear Matter Properties from the Soft-wall Holographic QCD Model

We investigate dense nuclear matter using the soft-wall holographic QCD model, incorporating baryonic degrees of freedom via a homogeneous ansatz and the Chern-Simons (CS) term by regarding baryons as solitons. By solving the coupled equations of motion for the gauge, scalar, and gravitational fields under finite chemical potential, we analyzed the partially chiral symmetry restoration at densities and the equation of state up to several times of the saturation density. Utilizing this equation of state in neutron star simulations, we predict a maximum mass M_\rmmax^ \sim 2.3\ M_\odot^ and radii R_1.4^ \sim 12.5 km, aligning with recent astrophysical observations. This study provides a self-consistent description of the thermodynamic behavior and dense celestial structure of high-density nuclear matter under holographic framework.
