- 論文の詳細を見る
Two-flavor (up and down) quark matter in the instanton vacuum is investigated using a mean-field approximation at T=0. Electric charge neutrality is imposed for β-equilibrated quark matter. At finite chemical potential, a new charge neutral mixed phase is found between the chiral symmetry broken (CC) phase and the 2-flavor color superconducting (2SC) phase. The mixed phase is a mixture of a negatively charged CC subphase and a positively charged 2SC subphase with the appropriate volume ratio in a uniform electron gas. In addition, particle number densities, the effect of a finite current quark mass on the phase structure, the quark matter equation of state and compact stars are also investigated in this model.
