Unravelling the nonlinear ideal density response of many-body systems
Panagiotis Tolias, Tobias Dornheim, Zhandos A. Moldabekov +1
Nonlinear density response theory is revisited focusing on the harmonically perturbed finite temperature uniform electron gas. Within the non-interacting limit, brute force quantum…
Energy response and spatial alignment of the perturbed electron gas
Tobias Dornheim, Panagiotis Tolias, Zhandos Moldabekov +1
We present extensive new \emph{ab initio} path integral Monte Carlo (PIMC) simulations of the harmonically perturbed uniform electron gas (UEG) for different densities and temperat…
Linear-response time-dependent density functional theory approach to warm dense matter with adiabatic exchange--correlation kernels
Zhandos A. Moldabekov, Michele Pavanello, Maximilian P. Boehme +2
We present a new methodology for the linear-response time-dependent density functional theory (LR-TDDFT) calculation of the dynamic density response function of warm dense matter i…
Extraction of the frequency moments of spectral densities from imaginary-time correlation function data
Tobias Dornheim, Damar C. Wicaksono, Juan E. Suarez-Cardona +5
We introduce an exact framework to compute the positive frequency moments of different dynamic properties from imaginary-time quantum Monte Carlo…
The ion potential in warm dense matter: wake effects due to streaming degenerate electrons
Zhandos Moldabekov, Patrick Ludwig, Michael Bonitz +1
The effective dynamically screened potential of a classical ion in a stationary flowing quantum plasma at finite temperature is investigated. This is a key quantity for thermodynam…
Fermionic path integral Monte Carlo results for the uniform electron gas at finite temperature
V. S. Filinov, V. E. Fortov, M. Bonitz +1
The uniform electron gas (UEG) at finite temperature has recently attracted substantial interest due to the epxerimental progress in the field of warm dense matter. To explain the…
