Outline of Research at the Start

共鳴非弾性X線散乱(RIXS) は運動量とエネルギーの両方を分解して電荷・スピン・軌道励起の全体像を明らかにすることができる。そのRIXS に時間分解機能を付加しようという実験が、自由電子レーザーの発展と歩調を合わせて世界各地で始まっている。本研究では、今後大きな発展が期待される相関電子系に対する時間分解RIXSに着目し、実験に先立って理論からの提案を行う。

Outline of Final Research Achievements

Resonant inelastic x-ray scattering experiments after irradiation of excitation light to materials with strong electron-electron interactions have begun to be performed around the world to investigate the dynamics of charge and spin in photoexcited materials. The purpose of this study is to make a theoretical proposal prior to such experiments. We investigate the magnetic excitation dynamics after pump light irradiation for a two-dimensional Mott insulator on a square lattice, which is typical of strongly correlated systems, using large-scale numerical calculations, and present a new proposal for the time-resolved resonant inelastic x-ray scattering experiments.

Academic Significance and Societal Importance of the Research Achievements

時間分解共鳴非弾性X線散乱実験を用いた光励起された相関電子物質の研究は始まったばかりであり、今後大きな発展が期待される。残念ながら日本には相関電子物質に対する時間分解共鳴非弾性X線散乱実験のプロジェクトはないが、本理論研究において提案した実験が今後計画されれば、この分野の発展に寄与できると考えられる。
