| + | During this workshop, we will teach a group of PhD students and Post-Docs how to calculate several spectroscopies on different materials, ranging from strongly correlated to weakly correlated, using density functional theory, crystal-field theory, ligand field theory and the combination of density functional theory and the later methods. The main code used will be Quanty ([[http://www.quanty.org|www.quanty.org]]). | ||

| A 1 1/2 hour lecture introducing the basics of various core level spectroscopies (XAS, RXD, RIXS) on transition metal compounds. The lecture starts by introducing (correlated) transition metal compounds, why they are interesting, what are the open questions and how one can use core level spectroscopy to gain more insight into these materials and their physical properties. The lecture focusses on the relation between x-ray absorption (XAS), resonant elastic x-ray diffraction (RXD) and resonant inelastic x-ray scattering (RIXS). In the first half the basis properties of XAS are discussed, introducing the optical selection rules and the difference between band/continuum excitations and excitons. It is briefly discussed how one can calculate XAS spectra, as well as the sum-rules relating the integrated intensity to ground-state expectation values. Polarization dependence is discussed by introducing the optical conductivity tensor (at x-ray frequencies), which then can be naturally extended to the scattering tensor. Dynamical effects in diffraction are discussed. The lecture ends with a discussion of resonant inelastic x-ray scattering. | A 1 1/2 hour lecture introducing the basics of various core level spectroscopies (XAS, RXD, RIXS) on transition metal compounds.
