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…
Effect of on-site Coulomb repulsion on ferromagnetic fluctuations in heavily over-doped cuprates
Shingo Teranishi, Kazutaka Nishiguchi, Seiji Yunoki +1
We theoretically study ferromagnetic (FM) fluctuations that are experimentally observed in the heavily overdoped region of cuprate superconductors. To explore the origin of FM fluc…
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…
An enhancement mechanism of two-particle exchange interactions in single- and multi-layer cuprate superconductors
Shingo Teranishi, Satoaki Miyao, Kazutaka Nishiguchi +1
To explore material dependence of layered cuprate superconductors, we examine effective two-particle interactions for Hg1201 and Tl1201, where Tl1201 having a nearly half value of…
Self-doping effect arising from electron correlations in multi-layer cuprates
Kazutaka Nishiguchi, Shingo Teranishi, Koichi Kusakabe
A self-doping effect between outer and inner CuO planes (OPs and IPs) in multi-layer cuprate superconductors is studied. When one considers a three-layer tight-binding model of…
