Analyzing X-ray Thomson scattering experiments of warm dense matter in the imaginary-time domain: theoretical models and simulations
Tobias Dornheim, Jan Vorberger, Zhandos Moldabekov +1
The rigorous diagnostics of experiments with warm dense matter (WDM) is notoriously difficult. A key method is given by X-ray Thomson scattering (XRTS), but the interpretation of X…
Spin-resolved density response of the warm dense electron gas
Tobias Dornheim, Jan Vorberger, Zhandos Moldabekov +1
We present extensive new \emph{ab initio} path integral Monte Carlo (PIMC) results for the spin-resolved density response of the uniform electron gas (UEG) at warm dense matter con…
Electronic pair alignment and roton feature in the warm dense electron gas
Tobias Dornheim, Zhandos Moldabekov, Jan Vorberger +2
The study of matter under extreme densities and temperatures as they occur e.g. in astrophysical objects and nuclear fusion applications has emerged as one of the most active front…
Density-Functional-Theory Perspective on the Non-Linear Response of Correlated Electrons Across Temperature Regimes
Zhandos Moldabekov, Jan Vorberger, Tobias Dornheim
We explore a new formalism to study the nonlinear electronic density response based on Kohn-Sham density functional theory (KS-DFT) at partially and strongly quantum degenerate reg…
Nonlinear electronic density response of the warm dense electron gas: multiple perturbations and mode coupling
Tobias Dornheim, Jan Vorberger, Zhandos Moldabekov +1
We present extensive new ab initio path integral Monte Carlo (PIMC) results for an electron gas at warm dense matter conditions that is subject to multiple harmonic perturbations.…
Path Integral Monte Carlo Simulations of liquid He without Fixed Nodes: Structural Properties and Collective Excitations
Tobias Dornheim, Zhandos Moldabekov, Jan Vorberger +1
We present extensive new \emph{ab initio} path integral Monte Carlo (PIMC) simulations of normal liquid He without any nodal constraints. This allows us to study the effects of…
