论文摘要
手性$ d $ - 波超导率已在多种不同的材料中提出，但是在很大程度上缺乏特征性的实验指纹。我们表明，在状态的局部密度和总磁矩的情况下，四足动物量身定量的无态涡旋易于形成并提供手性$ d $ - 波状态的独特签名。它们在正磁场和负磁场中的异常性进一步导致了额外的自发对称性破坏，从而产生了时间反转对称性破坏，手性超导性和Chern数的明确证据。
Chiral $d$-wave superconductivity has been proposed in a number of different materials, but characteristic experimental fingerprints have been largely lacking. We show that quadruply quantized coreless vortices are prone to form and offer distinctive signatures of the chiral $d$-wave state in both the local density of states and the total magnetic moment. Their dissimilarity in positive versus negative magnetic fields further leads to additional spontaneous symmetry breaking, producing clear evidence of time-reversal symmetry breaking, chiral superconductivity, and the Chern number.
