Outline of Final Research Achievements

We have developed the theory of the Resonant Inelastic X-ray Scattering (RIXS) on transition metal compounds such as high-Tc cuprates. We have demonstrated theoretically the difference of the Cu L-edge RIXS between hole- and electron-doped cuprates. We have shown a characteristic dependence on hole concentration in the Ni K-edge RIXS on Ni impurity in cuprates. We have also discussed theoretically the inelastic x-ray scattering on iron pnictides and the Cr L-edge RIXS on Chromium.
