X-Ray Spectroscopy

What

• Core level X-ray absorption spectra (XAS): X-ray absorption fine structure (XAFS), X-ray absorption near edge structure (XANES), and X-ray magnetic circular dichroism (XMCD).
• X-ray scattering factors, X-ray emission spectra, non-resonant X-ray Raman scattering (XRS) and electron energy loss spectra (EELS).

Where

• Bulk, Surfaces and Nanostructures. Liquids.

How

• Real-space Green's function (RSGF) approaches including quasi-particle effects (GW), core-hole screening, and Debye-Waller factors.
• Additional many body effects treated with TDDFT, BSE, and spectral functions.
