多軌道反強磁性金属の典型であるクロム金属のスピン励起スペクトルと共鳴非弾性X線散乱スペクトルを、多軌道ハバード模型に対する平均場近似,乱雑位相近似、及び高速衝突近似により求め、それらスペクトルを予見した。

Chromium is a representative metal with spin density wave. In this study, spin excitation and L-edge resonant inelastic X-ray scattering spectra are obtained theoretically by using the multi-orbital Hubbard model with mean-field, randam phase, and first collision approximations.
