X-ray spectroscopy is a widely used technique in experimental and theoretical physics for studying electronic and chemical properties of materials. Theoretical approaches for studying x-ray absorption (XAS) and x-ray photoemision (XPS) properties are described by single particle Green’s function theory. In strongly correlated ...

X-ray absorption spectroscopy (XAS) and x-ray emission spectroscopy (XES) are element specific, bulk sensitive measures of local electronic structure. As such, they make an ideal probe of actinide 5f electrons, and are situated to answer important questions about actinide covalency. To this end, I have performed resonant ...
