Halogen control of magnetic competition in Kitaev candidate Ru ( Cl, Br)
Ryuta Iwazaki, Shinnosuke Koyama, Takashi Koretsune +2
The spin-orbital Mott insulators Ru ( Cl, Br) have attracted considerable attention as promising candidate materials for realizing a Kitaev spin liquid. In this study, we…
Material-based analysis of spin-orbital Mott insulators
Ryuta Iwazaki, Hiroshi Shinaoka, Shintaro Hoshino
We present a framework for analyzing Mott insulators using a material-based tight-binding model. We start with a realistic multiorbital Hubbard model and derive an effective model…
Spin-orbital model for fullerides
Ryuta Iwazaki, Shintaro Hoshino
The multiorbital Hubbard model in the strong coupling limit is analyzed for the effectively antiferromagnetic Hund's coupling relevant to fulleride superconductors with three orbit…
Exact Thermodynamic Properties of (1,1/2) Mixed Diamond Chains with Strong Single-Site Anisotropy
Ryuta Iwazaki, Kazuo Hida
The ground states and finite-temperature properties of mixed diamond chains with spins 1 and 1/2 are investigated in the limit of strong easy-axis anisotropy on the spin-1 sites. M…
Nature of superconducting fluctuation in photo-excited systems
Ryuta Iwazaki, Naoto Tsuji, Shintaro Hoshino
The photo-excited state associated with superconducting fluctuation above the superconducting critical temperature is studied based on the time-dependent Ginzburg-Laundau app…
