标题： Unconventional Hall Effect in Gapless Superconductors: Transverse Supercurrent Converted from Normal Current

摘要： 一个由超导体诱导的正常金属系统可以表现出无能隙超导态，该状态以分段费米面为特征，并已被实验证实。 在这种状态下，准粒子态在一个方向上保持无能隙，而在垂直方向上则打开超导能隙。 这种各向异性使无能隙超导体中出现了一种新的霍尔效应，称为超导霍尔效应（ScHE），其中由准粒子携带的纵向正常电流被转化为无耗散的横向超电流。 利用体材料的热力学方法和四探针设置下的量子输运理论，我们证明了这种效应的存在，并揭示了其内在来源为准粒子的贝里曲率。 预测的ScHE可以通过在无能隙超导体上进行的标准角分辨霍尔测量来实验验证。 显示英文摘要

摘要： A normal metallic system proximitized by a superconductor can exhibit a gapless superconducting state characterized by segmented Fermi surfaces, as confirmed experimentally. In such a state, quasiparticle states remain gapless along one direction, while a superconducting gap opens in the perpendicular direction. This anisotropy enables a novel Hall effect in gapless superconductors, termed the superconducting Hall effect (ScHE), where a longitudinal normal current carried by quasiparticles is converted into a dissipationless transverse supercurrent. Employing both the thermodynamic approach for bulk systems and quantum transport theory for a four-probe setup, we demonstrate the existence of this effect and reveal its intrinsic origin as the quasiparticle Berry curvature. The predicted ScHE can be experimentally verified via the standard angular-dependent Hall measurements performed on gapless superconductors.
