Nonreciprocal charge transport in two-dimensional noncentrosymmetric superconductors
Shintaro Hoshino, Ryohei Wakatsuki, Keita Hamamoto +1
Nonreciprocal charge transport phenomena are studied theoretically for two-dimensional noncentrosymmetric superconductors under an external magnetic field . Rashba superconducto…
Nonreciprocal current in noncentrosymmetric Rashba superconductors
Ryohei Wakatsuki, Naoto Nagaosa
Noncentrosymmetric superconductors with broken inversion symmetry offer rich physical phenomena such as the upper critical magnetic field beyond the Pauli limit and ma…
Proximity effect and Ising superconductivity in superconductor/transition metal dichalcogenide heterostructures
Ryohei Wakatsuki, K. T. Law
Recently, it was experimentally realized that 2D superconducting transition metal dichalcogenides (TMD) such as gated MoS and monolayer NbSe have in-plane upper critical ma…
Domain wall of a ferromagnet on a three-dimensional topological insulator
Ryohei Wakatsuki, Motohiko Ezawa, Naoto Nagaosa
Topological insulators (TIs) show rich phenomena and functions which can never be realized in ordinary insulators. Most of them come from the peculiar surface or edge states. Espec…
Fermion Fractionalization to Majorana Fermions in Dimerized Kitaev Superconductor
Ryohei Wakatsuki, Motohiko Ezawa, Yukio Tanaka +1
We study theoretically a one-dimensional dimerized Kitaev superconductor model which belongs to BDI class with time-reversal, particle-hole, and chiral symmetries. There are two so…
Majorana Fermions and Multiple Topological Phase Transition in Kitaev Ladder Topological Superconductors
Ryohei Wakatsuki, Motohiko Ezawa, Naoto Nagaosa
Motivated by the InSb nanowire superconductor system, we investigate a system where one-dimensional topological superconductors are placed in parallel. It would be simulated well b…
