Electron dynamic and static structure factors in warm dense matter from density functional theory — •Zhandos Moldabekov1 and Tobias Dornheim1, 2 — 1Institute of Radiation Physics, Helmholtz-Zentrum Dresden-Rossendorf (HZDR), D-01328 Dresden, Germany — 2Center for Advanced Systems Understanding (CASUS), D-02826 Görlitz, Germany
Understanding the behavior of warm dense matter is crucial for modeling compact astrophysical objects and advancing research in inertial confinement fusion. Density functional theory (DFT) is the standard theoretical tool used in this regime. We introduce a new approach that combines time-dependent DFT calculations of the dynamic structure factor with static DFT results for the density response [1], enabling accurate predictions of the electron-electron static structure factor in warm dense matter. We also present our recent methodological and computational advances in applying linear-response time-dependent DFT (LR-TDDFT) to calculate the electron dynamical structure factor [2-8].// [1] Z.
