Instantaneous-Frame Theory of Strongly Driven Parametric Gates
Kentaro Kubo, Shinichi Inoue, Jushin Tei +3
Parametric two-qubit gates using tunable couplers are a promising approach to scalable superconducting quantum processors. However, conventional theories formulated in the idle eig…
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…
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…
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…
Pairing symmetries of multiple superconducting phases in UTe2: Competition between ferromagnetic and antiferromagnetic fluctuations
Jushin Tei, Takeshi Mizushima, Satoshi Fujimoto
The putative spin-triplet superconductor UTe2 exhibits multiple superconducting phases under applied pressure [D. Braithwaite et al., Commun. Phys. 2, 147 (2019)]. The clarificatio…
Possible Realization of Topological Crystalline Superconductivity with Time-Reversal Symmetry in UTe2
Jushin Tei, Takeshi Mizushima, Satoshi Fujimoto
The recent measurement of the de Haas-van Alphen effect in the spin-triplet superconductor UTe2 [D. Aoki et al., J. Phys. Soc. Jpn. 91, 083704 (2022)] supports cylindrical electron…
