"Theory of Resonant X-Ray Scattering with Applications to high-Tc Cuprates"
 Slideshow (PDF)
Resonant x-ray scattering has recently become an exceptionally powerful and versatile technique. However, its theoretical foundation lags behind experiments. In particular, experiments on conducting phases are often interpreted in terms of local models based on Mott insulators. I will discuss a method that handles arbitrary band structures and includes the effect of the positively-charged core hole. Next, I will compare our results to experiments on conducting and charge density wave cuprate phases and show how simple quasiparticle physics yields signatures previously considered evidence of more exotic behavior.
