We investigate the magnetic response of nematic superconductors, presenting a new approach to find vortex and skyrmion structures beyond symmetry-constraining Ansätze. Using this approach we show that nematic superconductors form distinctive skyrmion stripes. Our approach lends itself to accurate determination of the field distribution for muon spin rotation probes. We use this to show that the skyrmion structure manifests as a double peak in the field distribution, markedly different from the signal of standard vortex lattices.

向列超导体的磁响应:斯格明子条纹及其在 μ 子自旋弛豫实验中的特征

我们研究了向列超导体的磁响应,提出了一种寻找超越对称约束 Ansätze 的涡旋和斯格明子结构的新方法。使用这种方法,我们证明向列超导体形成独特的斯格明子条纹。我们的方法有助于准确确定μ子自旋旋转探针的场分布。我们用它来表明斯格明子结构在场分布中表现为双峰,与标准涡旋晶格的信号明显不同。
