We are interested in first-principles calculations of near-edge x-ray spectra, including absorption and resonant inelastic scattering. Our goal is predictive modeling where the kind and location of atoms are the only adjustable parameters. We make use of and contribute to the ocean code.
We have two main interests in theoretical spectroscopy. First, we help with the interpretation and understanding of experimental measurements. Calculations allow for precise control over the sample, giving a concrete connection between structure and spectra. Second, calculated x-ray spectra provide validation and critiques of the underlying approximations in density functional theory, the workhorse of computational materials by design.
