Charge Neutrality Effects on 2-flavor Color Superconductivity

The effect of electric and color neutrality on 2-flavor color superconductivity has been investigated. It has been found that the effect of the charge neutrality on a 2-flavor quark system is very different from that on a 3-flavor system. The BCS diquark pair in 2-flavor color superconducting phase...

Description
Summary:The effect of electric and color neutrality on 2-flavor color superconductivity has been investigated. It has been found that the effect of the charge neutrality on a 2-flavor quark system is very different from that on a 3-flavor system. The BCS diquark pair in 2-flavor color superconducting phase has been largely reduced by the large Fermi momentum of electron, the diquark condensate first increases with the increasing of quark's chemical potential \(\mu\),then decreases rapidly and finally disappears at about \(\mu=535MeV\), at which the thermodynamic potential equals to that in the neutral normal 2-flavor quark matter.
