The quadratic density response function for non-interacting fermions at arbitrary temperature
Pontus Svensson, Jan Vorberger, Zhandos A. Moldabekov +5
We develop and implement the quadratic density response function of non-interacting fermions at arbitrary temperature, frequencies, and wave vectors. Starting from a Green's functi…
Reconciling chemical models of X-ray Thomson Scattering with the Bethe -sum rule
Maximilian P. Böhme, Paul Hamann, Veronika A. Kruse +9
X-ray Thomson scattering (XRTS) is a key diagnostic for high-energy-density plasmas, which can exhibit significant quantum effects even at elevated temperatures. XRTS experiments a…
Prediction of a roton-type feature in warm dense hydrogen
Paul Hamann, Linda Kordts, Alexey Filinov +3
In a recent Letter [T. Dornheim \textit{et al.}, Phys. Rev. Lett. \textbf{121}, 255001 (2018)], it was predicted on the basis of \textit{ab initio} quantum Monte Carlo simulations…
Ab initio results for the plasmon dispersion and damping of the warm dense electron gas
Paul Hamann, Jan Vorberger, Tobias Dornheim +2
Warm dense matter (WDM) is an exotic state on the border between condensed matter and dense plasmas. Important occurrences of WDM include dense astrophysical objects, matter in the…
