- 論文の詳細を見る
Effects of charged-pion(π^c) condensation on neutron ^3P_2 superfluidity are investigated by taking account of realistic aspects of the π^c condensation realized at high density in neutron star interior. Coexistence of the two hadronic condensates is formulated as the pairing correlation in the system of quasi-neutrons described as a superposition of neutron and proton by adopting an aligned angular-momemtum coupling for the ^3P_2 pairing, under the restriction of the baryonic degrees of freedom to the nucleonic one. We find a mild effect of the π^c condensation due to which, compared with the case without the π^c condensation, the critical temperature of ^3P_2 superfluidity is slightly larger at densities up to about three times the nuclear density, and becomes smaller as density goes higher. Discussion is given concerning the dependence of the results on the π^c condensation parameters, effective mass and so forth.
