Symmetry energy of dense matter in holographic QCD

TL;DR

This paper investigates the behavior of nuclear symmetry energy in dense matter using a holographic QCD model, revealing a monotonic increase with density and a specific power law at low densities.

Contribution

It introduces a holographic QCD approach with two flavor branes to analyze the symmetry energy in dense nuclear matter, highlighting its density dependence.

Findings

Symmetry energy increases monotonically with density.

At low densities, symmetry energy follows a $ ho^{1/2}$ power law.

The model provides insights into dense matter properties in QCD.

Abstract

We study the nuclear symmetry energy of dense matter using holographic QCD. To this end, we consider two flavor branes with equal quark masses in a D4/D6/D6 model. We find that at all densities the symmetry energy monotonically increases. At small densities, it exhibits a power law behavior with the density, $E_{\rm sym} \sim \rho^{1/2}$.
