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.
我们研究了向列超导体的磁响应,提出了一种新方法来寻找超越对称约束方法的涡旋和斯格明子结构。使用这种方法,我们表明向列超导体形成了独特的斯格明子条纹。我们的方法适用于准确确定μ子旋转探测的磁场分布。我们利用这一点表明,斯格明子结构表现为磁场分布中的双峰,与标准涡旋晶格的信号明显不同。
