Resonant Inelastic X ray Scattering and its Application to High Temperature Superconductivity

In this talk I will introduce the relatively new experimental technique of resonant inelastic x ray scattering RIXS for the study of excitations in solids This technique became every popular in recent years due to few technical and scientific advances and is now competing with neutron scattering I will emphasize the aspects of the technique we understand and those that we donb t Finally I will demonstrate the application of RIXS to
