摘要:

计算了正常金属/绝缘体/超导体(N/I/S)结的隧穿电导谱,以确定隧穿谱在拓扑超导研究中的潜力。拓扑超导体的特殊之处在于它能形成无带隙的边缘态。由于N/I/S结的电导对这些边缘态的形成很敏感,因此可以通过边缘态检测来识别拓扑超导性。在此,费米表面各向异性和所施加的磁场的电导谱的影响进行了分析,收集的迹象,可以帮助识别实际材料的拓扑性质。

英文摘要:

Tunneling conductance spectra of normal metal/insulator/superconductor (N/I/S) junctions are calculated to determine the potential of tunneling spectroscopy in investigations of topological superconductivity. Peculiar feature of topological superconductors is the formation of gapless edge states in them. Since the conductance of N/I/S junctions is sensitive to the formation of these edge states, topological superconductivity can be identified through edge-state detection. Herein, the effects of Fermi surface anisotropy and an applied magnetic field on the conductance spectra are analyzed to gather indications that can help to identify the topological nature of actual materials.
