Query: Exact solution of a variety of X-ray probes in the Falicov-Kimball model
  with dynamical mean-field theory   We examine core-level X-ray photoemission spectroscopy (XPS), X-ray
absorption near-edge spectroscopy (XANES) and X-ray emission spectroscopy (XES)
in the Falicov-Kimball model by using the exact solution from dynamical
mean-field theory. XPS measures the core-hole propagator, XANES measures the
absorption of X-rays when the core electron is excited to an unoccupied
electronic state of the solid, and not emitted, and XES measures the spectra of
light emitted as electrons fill the core-hole state created via some form of
X-ray excitation. These three spectra are closely related to one another and
display orthogonality catastrophe behavior at T=0. We illustrate how to
evaluate these spectra efficiently at finite temperature, with a primary focus
on the details of XANES.
