Description
I will then give some example of non-resonant scattering of X-rays. I will show in particular how this gives conceptually similar results to inelastic neutron scattering (INS) in the case of phonons. With example on superconductors, I will highlight the technical difference justifying the choice of X-ray or neutron as probe, depending on the material, the environment and the specific details of the phonon dispersion of interest.
In the second part of the lecture I will focus on the resonant scattering of X-rays, and the information that can be obtained with Resonant Inelastic X-ray Scattering (RIXS), in particular why this will give access to magnetic excitation and compare the results to INS for spin-wave dispersion in cuprate high temperature superconductors.
