Phase-dependent Andreev molecules and superconducting gap closing in coherently coupled Josephson junctions
Sadashige Matsuo, Takaya Imoto, Tomohiro Yokoyama +8
The Josephson junction (JJ) is an essential element of superconducting (SC) devices for both fundamental and applied physics. The short-range coherent coupling of two adjacent JJs…
Bulk odd-frequency pairing in the superconducting Su-Schrieffer-Heeger model
Shun Tamura, Sho Nakosai, Annica M. Black-Schaffer +2
The Su-Schrieffer-Heeger model describes fermions that hop on a one-dimensional chain with staggered hopping amplitude, where the unit cell contains two sites, or two sublattices.…
Theory of Josephson Current on a Magnetically Doped Topological Insulator
Tsubasa Toki, Sho Nakosai, Yukio Tanaka +1
Proximity induced superconducting states in the surface of magnetically doped topological insulators can host chiral Majorana modes. We consider a Josephson junction in that system…
Magnetic Monopole Supercurrent through a Quantum Spin Ice Tunnel Junction
Sho Nakosai, Shigeki Onoda
Magnetic monopoles are hypothetical particles that may exist as quantized sources and sinks of the magnetic field. In materials, they may appear in an emergent quantum electrodynam…
Spontaneous modulation of superconducting phase in Kitaev ladder
Sho Nakosai, Yukio Tanaka, Tai Kai Ng +1
We study theoretically the two Kitaev chains put in parallel, i.e., Kitaev ladder, coupled by Josephson junction. The -junction between the Majorana bound states at the ends of…
Skyrmion-induced bound states in a superconductor
Sergey S. Pershoguba, Sho Nakosai, Alexander V. Balatsky
We consider a superconductor proximity coupled to a two-dimensional ferromagnetic film with a skyrmion texture. Using the T-matrix calculations and numerical modeling we calculate…
Two-dimensional p-wave superconducting states with magnetic moments on a conventional s-wave superconductor
Sho Nakosai, Yukio Tanaka, Naoto Nagaosa
Unconventional superconductivity induced by the magnetic moments in a conventional spin-singlet s-wave superconductor is theoretically studied. By choosing the spin directions of t…
Majorana bound states and non-local spin correlations in a quantum wire on an unconventional superconductor
Sho Nakosai, Jan Carl Budich, Yukio Tanaka +2
We study theoretically the proximity effect of a one-dimensional metallic quantum wire (in the absence of spin-orbit interaction) lying on top of an unconventional superconductor.…
Topological superconductivity in bilayer Rashba system
Sho Nakosai, Yukio Tanaka, Naoto Nagaosa
We theoretically study a possible topological superconductivity in the interacting two layers of Rashba systems, which can be fabricated by the hetero-structures of semiconductors…
