We demonstrate that two-dimensional chiral superconductors on curved surfaces spontaneously develop magnetic flux. This geometric Meissner effect provides an unequivocal signature of chiral superconductivity, which could be observed in layered materials under stress. We also employ the effect to explain some puzzling questions related to the location of zero-energy Majorana modes.
我们证明了曲面二维手性超导体中会自发产生磁场。这种几何迈斯纳效应为手征超导提供了一个明确的特征,可以在手性层状材料在受压时观察到。我们还利用这一效应来解释与零能马约拉纳模位置有关的一些难题。
