Entropy for Color Superconductivity in Quark Matter

Abstract

We study a model for color superconductivity with both three colors and massless flavors including quark pairing. By using the Hamiltonian in the color-flavor basis we can calculate the quantum entropy. From this we are able to further investigate the phases of the color superconductor, for which we find a rather sharp transition to color superconductivity above a chemical potential around $290$MeV.Comment: 10 pages, 2 eps-figure
