Reconciling chemical models of X-ray Thomson Scattering with the Bethe -sum rule
Maximilian P. Böhme, Maximilian P. Böhme, Paul Hamann +10
The paper extends the Chihara decomposition used in X‑ray Thomson scattering diagnostics to include explicit bound‑bound transitions and an exact bound‑free treatment, ensuring com…
Kinetic energy from the cubic sum rule of the dynamic structure factor
Fotios Kalkavouras, Panagiotis Tolias, Sebastian Schwalbe +6
The third frequency moment sum rule of the dynamic structure factor is explored for the first time as an alternative estimator of the kinetic energy of quant…
X-Ray Diagnostics Analysis Verification and Exploration (xDAVE) Code for the Prediction and Interpretation of X-Ray Thomson Scattering Experiments
Hannah M. Bellenbaum, Dave A. Chapman, Maximilian P. Böhme +8
X-ray Thomson scattering (XRTS) is a common diagnostic used in the warm dense matter (WDM) regime to estimate plasma parameters like density, temperature and charge state. Experime…
Spectral Deconvolution without the Deconvolution: Extracting Temperature from X-ray Thomson Scattering Spectra without the Source-and-Instrument Function
Thomas Gawne, Alina Kononov, Andrew Baczewski +7
X-ray Thomson scattering (XRTS) probes the dynamic structure factor of the system, but the measured spectrum is broadened by the combined source-and-instrument function (SIF) of th…
Static linear density response from X-ray Thomson scattering measurements: a case study of warm dense beryllium
Sebastian Schwalbe, Hannah Bellenbaum, Tilo Döppner +8
Linear response theory is ubiquitous throughout physics and plays a central role in the theoretical description of warm dense matter -- an extreme state that occurs within compact…
Green's function perspective on the nonlinear density response of quantum many-body systems
Jan Vorberger, Tobias Dornheim, Maximilian P. Böhme +2
We derive equations of motion for higher order density response functions using the theory of thermodynamic Green's functions. We also derive expressions for the higher order gener…
