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…
Ab initio path integral Monte Carlo study of the 2D uniform electron liquid at finite temperatures
Tobias Dornheim, Fotios Kalkavouras, Paul Hamann +3
The paper presents extensive ab initio path integral Monte Carlo simulations of the two‑dimensional uniform electron gas over a wide range of densities and temperatures, analyzing…
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…
Reweighting Estimators for Density Response in Path Integral Monte Carlo: Applications to linear, nonlinear and cross-species density response
Pontus Svensson, Thomas Chuna, Jan Vorberger +5
We present density response estimators for Monte Carlo simulations that are based on a reweighting procedure, where the samples of an unperturbed system are used to estimate the pr…
Monte-Carlo Event Generation for X-Ray Thomson Scattering Analysis
Uwe Hernandez Acosta, Thomas Gawne, Jan Vorberger +6
A key diagnostic in warm-dense matter (WDM) experiments is X-ray Thomson scattering (XRTS), but its interpretation is often limited by complex instrument effects and the high compu…
Mermin's dielectric function and the f-sum rule
Thomas Chuna, Jan Vorberger, Thomas Gawne +2
Mermin's dielectric function [N.D. Mermin, Phys. Rev. B 1, 2362 (1970)] is widely assumed to satisfy the f-sum rule because he constrains his ansatz with the continuity equation. H…
