Equation of state for holographic nuclear matter as instanton gas

Blog Article

In a holographic model, which was used to investigate the color superconducting phase of QCD, a dilute gas of instantons is introduced to study the nuclear matter.The free energy of the nuclear Dinner Knives matter is computed as a function of the baryon chemical potential in the probe approximation.Then the equation of state is obtained at low temperature.Using the equation of state for the nuclear matter, the Tolman-Oppenheimer-Volkov equations for a cold compact star are solved.We find the mass-radius relation of the star, which is similar to the one for quark star.

This similarity implies that the instanton gas given here is a Formation kind of self-bound matter.
