Quasi-elastic scattering under short-range order: the linear regime and beyond
XPCS is a coherent scattering technique, it therefore measures the pair-correlation function of the electrons. Following the successful
experimental realisation it became a necessity to understand the influence of short-range order on the measured linewidths/correlation times.
This paper derives the theory in the limit of vanishing interactions, and shows by way of Monte Carlo-simulations what happens with stronger interactions.
