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…
Magnetic and Orbital Order in (MnO)/(MnO) Superlattices Studied via a Double-Exchange Model with Strain
Shuai Dong, Qinfang Zhang, Seiji Yunoki +2
The two-orbital double-exchange model is employed for the study of the magnetic and orbital orders in (MnO)/(MnO) (: rare earths; : alkaline earths)…
Unexpected Anisotropic Two Dimensional Electron Gas at the LaAlO3/SrTiO3 (110) Interface
A. Annadi, X. Wang, K. Gopinadhan +17
The observation of a two dimensional electron gas (2DEG) (1, 2), superconductivity (3, 4), magnetic effects (5) and electronic phase separation (6-8) at the interfaces of insulatin…
Strain-engineered magnetic order in (LaMnO)/(SrMnO) superlattices
Qinfang Zhang, Shuai Dong, Baolin Wang +1
Using first-principles calculations based on the density functional theory, we show a strong strain dependence of magnetic order in (LaMnO)/(SrMnO) (001) sup…
Absence of a Spin Liquid Phase in the Hubbard Model on the Honeycomb Lattice
Sandro Sorella, Yuichi Otsuka, Seiji Yunoki
A spin liquid is a novel quantum state of matter with no conventional order parameter where a finite charge gap exists even though the band theory would predict metallic behavior.…
Large spectral weight transfer in optical conductivity of SrTiO induced by intrinsic vacancies
Teguh C. Asmara, Xiao Wang, Iman Santoso +11
The optical conductivity () of SrTiO for various vacancies has been systematically studied using a combination of ultraviolet - vacuum ultraviolet (UV-VUV) reflectivit…
