Abstract:

Coexistent aspect of neutron 3P2 superfluidity under the well-developed π0 condensation in neutron star matter, which has been shown in a previous work, is confirmed in such a framework that two-dimensional character of this pairing correlation realized in the [ALS] (Alternating-Layer-Spin) phase is transparent in every step of calculations. Aligned pairing scheme is naturally introduced as the most important one under the well-developed [ALS] structure, which takes efficiently the attractive effect of spin-orbit force in the 3P2 state. Energy gap equation obtained after a suitable Bogoliubov transformation has a simple form reflecting two-dimensional character of the aligned pairing. Numerical calculations by the use of an approximate version of realistic local potentials show that energy gaps of the aligned pairing are smaller by a factor of 2 ∼3 than those of the 3P2 pairing realized from the spherical Fermi gas, and the resulting critical temperatures are not so different. Dependences on the interaction, density and the parameters characterizing the [ALS] structure and various additional effects are discussed.
