Spin susceptibility for orbital-singlet Cooper pair in the three-dimensional SrRuO superconductor
Yuri Fukaya, Tatsuki Hashimoto, Masatoshi Sato +2
We study the spin susceptibility of the orbital-singlet pairings, including the spin-triplet/orbital-singlet/-wave representation proposed by Suh \textit{et al}., [H.\ G.\…
Superconductivity in the nonsymmorphic line-nodal compound CaSb
Atsutoshi Ikeda, Mayo Kawaguchi, Shun Koibuchi +5
We found superconductivity in CaSb with the transition temperature of 1.7 K by means of electrical-resistivity, magnetic-susceptibility, and specific-heat measurements. This ma…
Dominant -wave superconducting gap in PdTe observed by tunneling spectroscopy on side-junctions
J. A. Voerman, J. C. de Boer, T. Hashimoto +3
We have fabricated superconductor-normal metal side-junctions with different barrier transparencies out of PdTe crystalline flakes and measured the differential conductance spe…
Tunability of Andreev levels via spin-orbit coupling in Zeeman-split Josephson junctions
Tatsuki Hashimoto, Alexander A. Golubov, Yukio Tanaka +1
We study Andreev reflection and Andreev levels in Zeeman-split superconductor/Rashba wire/Zeeman-split superconductor junctions by solving the Bogoliubov de-Gennes eq…
Superconductivity in doped Dirac semimetals
Tatsuki Hashimoto, Shingo Kobayashi, Yukio Tanaka +1
We theoretically study intrinsic superconductivity in doped Dirac semimetals. Dirac semimetals host bulk Dirac points, which are formed by doubly degenerate bands, so the Hamiltoni…
Surface electronic state of superconducting topological crystalline insulator
Tatsuki Hashimoto, Keiji Yada, Masatoshi Sato +1
We study the surface state of a doped topological crystalline insulator in the superconducting state. Motivated by SnInTe, we consider fully gapped pair potentials and…
Effect of Fermi surface evolution on superconducting gap in superconducting topological insulator
Tatsuki Hashimoto, Keiji Yada, Ai Yamakage +2
We study bulk electronic states of superconducting topological insulator, which is the promising candidate for topological superconductor. Recent experiments suggest that the three…
Bulk electronic state of superconducting topological insulator
Tatsuki Hashimoto, Keiji Yada, Ai Yamakage +2
We study electronic properties of a superconducting topological insulator whose parent material is a topological insulator. We calculate the temperature dependence of the specific…
