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…
Dielectric formalism of the 2D uniform electron gas at finite temperatures
Fotios Kalkavouras, Tobias Dornheim, Paul Hamann +1
We present a comprehensive analysis of the two-dimensional uniform electron gas (2D-UEG or more commonly 2DEG) at finite temperature, spanning a broad range of densities / coupling…
Thermal PBE in warm dense matter: Does it matter and is it accurate?
Kushal Ramakrishna, Mani Lokamani, Zhandos A. Moldabekov +3
Conditional probability density functional theory has recently been used to derive the temperature dependence of the Perdew-Burke-Ernzerhof (PBE) generalized gradient approximation…
A Momentum-Resolved X-ray Thomson Scattering Benchmark of Electronic-Response Models in Warm Dense Aluminium
Dmitrii S. Bespalov, Ulf Zastrau, Zhandos A. Moldabekov +58
The robust diagnosis of conditions generated in warm dense matter (WDM) experiments remains a persistent challenge. Here we describe the measurement of shock-compressed aluminium a…
