Dynamical Structure Factor in High Energy Density Plasmas and Application to X-Ray Thomson Scattering

The Dynamical Structure Factor (DSF) is a key observable in high energy density science that is directly measured e.g. using inelastic x-ray scattering techniques. The DSF delivers a wealth of information about macroscopic equation of state data (temperature of electrons and of ion species, average ionization states, electron density), collective and single-particle dynamics, static correlations, electron-ion collisions, and electronic structure. In a strongly coupled, partly degenerate many-body system, such as warm dense matter generated by intense laser-matter interaction and shock wave compression, calculations of the DSF are a formidable task.
