利用金兹堡-朗道理论,考虑了磁场对各向异性(/sup 3/P/sub 2/)中子超流体的影响。在强磁场中,配对态沿磁场方向有一个与角度相关的能隙。利用同伦理论的方法确定了/sup 3/P/sub 2/阶参量允许的拓扑稳定线缺陷。我们对线涡的自由能分析给出了一个与其他作者所得到的在核心区域外的单涡的质量不同的结构。
Using Ginzburg-Landau theory, we consider the effect of a magnetic field on the anisotropic (/sup 3/P/sub 2/) neutron superfluid. In a strong magnetic field, the pairing state has an angle-dependent energy gap with a node along the field direction. Methods of homotopy theory are used to determine the topologically stable line defects allowed by the /sup 3/P/sub 2/ order parameters. Our free-energy analysis of line vortices gives a qualitatively different structure to the single vortex, outside of the core region, from that obtained by other authors.
