Magnetic penetration depth in topological superconductors: Effect of Majorana surface states and application for UTe
Kazuki Akuzawa, Jushin Tei, Ryoi Ohashi +2
In this study, we examine how orbital degrees of freedom and Majorana surface states influence the magnetic penetration depth in the superconductor UTe. Using a two-orbital mod…
Theory of Andreev and shot noise spectroscopy for topological superconductors probed by -wave superconducting tips
Jushin Tei, Ryo Hanai, Satoshi Fujimoto +1
Scanning tunneling microscopy (STM) and spectroscopy (STS) with -wave superconducting tips has been widely applied to probe exotic superconductors, but its potential for investi…
Two-dimensional flat band on the (011) surface of UTe: Implication for STM measurements with a superconducting tip
Jushin Tei, Takeshi Mizushima, Satoshi Fujimoto
Scanning tunneling microscopy (STM) measurements have been extensively performed on the easily cleavable (011) surface of UTe, using both normal-metal and superconducting tips.…
Anisotropic paramagnetic response of topological Majorana surface states in the superconductor
Ryoi Ohashi, Jushin Tei, Yukio Tanaka +2
Identifying the superconducting gap symmetry and topological signatures in the putative spin-triplet superconductor is an important issue. Especially, a smoking-gun…
