Several Notes on the Topological Structure of the Superfluid 3~He System Surface

本文讨论在圆膜状和球面边界条件下,超流~3He系统诸相的纯表面缺陷的拓扑结构,给出相应的点缺陷和线缺陷的拓扑量子数.本文发现,边界条件对于~3He系统的拓扑结构的影响十分重要.

The topological structure of pure surface defects of different phases(A,A, B, B)of the superfluid 3He system under the boundary condition of sphere and circular membrane are studied. The topological quantum number for the respective pure surface defect is given. It is found that the influence of the boundary condition on the topological structure of the superfluid 3He system is significant.
