X-ray Thomson scattering absolute intensity from the f-sum rule in the imaginary-time domain
arxiv(2023)
摘要
We present a formally exact and simulation-free approach for the
normalization of X-ray Thomson scattering (XRTS) spectra based on the f-sum
rule of the imaginary-time correlation function (ITCF). Our method works for
any degree of collectivity, over a broad range of temperatures, and is
applicable even in nonequilibrium situations. In addition to giving us
model-free access to electronic correlations, this new approach opens up the
intriguing possibility to extract a plethora of physical properties from the
ITCF based on XRTS experiments.
