论文摘要
库珀对波函数的空间组方法扩展到III型的Shubnikov组，并应用于新发现的几乎铁磁超导体UTE2。对于Shubnikov组M'm，获得了一个非洲三胞胎SOP（超导顺序参数）。研究了三胞胎非整体SOP的节点结构，并显示在Shubnikov III对称性淋巴结结构中，ESP（相等自旋配对）状态在某些情况下是不稳定的，即添加复杂的相位绕组时的变化。确定了与M'M对称相对应的库珀对波函数的不可还原核心表现，并确定了与UTE2的所有实验数据相对应的。
The space-group approach to the wavefunction of a Cooper pair is extended to Shubnikov groups of type III and applied to newly discovered nearly ferromagnetic superconductor UTe2. A nonunitary triplet SOP (superconducting order parameter), manifested experimentally, was obtained for Shubnikov group m'm'm . The nodal structure of triplet nonunitary SOP is investigated and it was shown that in the case of Shubnikov III symmetry nodal structure of ESP (equal spin pairing) state is in some cases unstable, i.e. changes when a complex phase winding is added. The irreducible corepresentations of a Cooper pair wave function corresponding to m'm'm symmetry and to all experimental data for UTe2 are identified.
