论文摘要
自旋敏感性是表征非常规超导体中顺序参数对称性的重要探针。其中,在寻求拓扑超导率的背景下,非正式的三胞胎超导体最近引起了很多关注。在这里,我们得出了一个通用公式,用于在非磁性的,中心对称材料的单波段模型中非洲三胞胎超导体的自旋敏感性,并具有强旋转轨道耦合。我们使用它来批判性地评估某些材料中非洲三胞胎超导性的实验性主张。
The spin susceptibility is an important probe to characterize the symmetry of the order parameter in unconventional superconductors. Among them, nonunitary triplet superconductors have attracted a lot of attention recently in the context of the search for topological superconductivity. Here, we derive a general formula for the spin susceptibility of nonunitary triplet superconductors within a single-band model of non-magnetic, centrosymmetric materials with strong spin-orbit coupling. We use it to critically assess experimental claims of nonunitary triplet superconductivity in some materials.
