Monte Carlo study of cuprate superconductors in a four-band - model: Role of orbital degrees of freedom
Hiroshi Watanabe, Tomonori Shirakawa, Kazuhiro Seki +4
Understanding the complex phase diagram of cuprate superconductors is a long-standing challenging problem. Recent studies have shown that orbital degrees of freedom, both Cu …
Unified description of cuprate superconductors using four-band - model
Hiroshi Watanabe, Tomonori Shirakawa, Kazuhiro Seki +4
In the 35 years since the discovery of cuprate superconductors, we have not yet reached a unified understanding of their properties, including their material dependence of the 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…
Monte Carlo study of an unconventional superconducting phase in Ir-oxide J_{eff}=1/2 Mott insulators induced by carrier doping
Hiroshi Watanabe, Tomonori Shirakawa, Seiji Yunoki
Based on a microscopic theoretical study, we show that novel superconductivity is induced by carrier doping in layered perovskite Ir oxides where a strong spin-orbit coupling cause…
Theoretical Study on Superconductivity in Boron-Doped Diamond
T. Shirakawa, S. Horiuchi, Y. Ohta +1
We consider superconductivity in boron (B) doped diamond using a simplified model for the valence band of diamond. We treat the effects of substitutional disorder of B ions by the…
