Material Optimization of Potential High- Superconducting Single-layer Cuprates
Shingo Teranishi, Kazutaka Nishiguchi, Koichi Kusakabe
We investigated the material parameters of several single-layer cuprates, including those with fluorinated buffer layers, with the aim of identifying possible high-temperature supe…
Possible superconductivity induced by a large spin-orbit coupling in carrier doped iridium oxide insulators: A weak coupling approach
Kazutaka Nishiguchi, Tomonori Shirakawa, Hiroshi Watanabe +2
We study possible superconductivity in a carrier-doped iridium oxide insulator SrIrO based on an effective three-orbital Hubbard model on the square lattice wi…
Tunable induced magnetic moment and in-plane conductance of graphene in Ni/graphene/Ni nano-spin-valve-like structure: a first principles study
Yusuf Wicaksono, Shingo Teranishi, Kazutaka Nishiguchi +1
This study theoretically investigated the magnetic properties and electronic structure of a graphene-based nano-spin-valve-like structure. Magnetic nickel layers on both sides of t…
Superconductivity arising from layer-differentiation in multi-layer cuprates
Kazutaka Nishiguchi, Shingo Teranishi, Koichi Kusakabe +1
In order to theoretically identify the factors governing superconductivity in multi-layer cuprates, a three-layer Hubbard model is studied with the two-particle self-consistent (TP…
Material-dependent screening of Coulomb interaction in single-layer cuprates
Shingo Teranishi, Kazutaka Nishiguchi, Koichi Kusakabe
To explore material dependence of cuprate superconductors, we evaluate effective Coulomb interactions for Hg1201 and Tl1201, where Tl1201 having a nearly half value of T_c of Hg120…
