论文摘要
在金茨堡 - 兰道限制中，研究了在旋转的中子旋转三旋转超氟中没有单数核的可能质地。它是在整个单位电池上构造的，具有涡旋分布的非呈涡流的晶格。估计与该结构相关的自由能的上限，结果表明，与普通的线性奇异涡旋相比，在旋转中子恒星的核心中，非单明的涡旋更为可取。所研究的中子系统的顺序参数属于单一类。这意味着所考虑的超流体没有旋转极化，而无核心$^{3} $ p $ _ {2} $涡流没有磁化，这使得电子散射无效。出于同样的原因，也抑制了固定管。这可以影响超流体中子星的流体动力学。
In the Ginzburg-Landau limit, a possible texture without singular cores in a rotating neutron spin-triplet superfluid is studied. It is constructed the lattice of non-singular vortices with a vorticity diffusely distributed over the entire unit cell. The upper limit of the free energy associated with this structure is estimated, and the result shows that non-singular vortices are more preferable in the core of rotating neutron stars than ordinary linear singular vortices. The order parameter of the studied neutron system belongs to the unitary class. This implies that the superfluid under consideration does not have spin polarization and the core-less $^{3}$P$_{2}$ vortices do not have magnetization, which makes electron scattering by vortices ineffective. For the same reason, pinning with flux tubes is also suppressed. This can affect the hydrodynamics of superfluid neutron stars.
