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…

Orientational Effects in the Low Pair Continuum of Aluminium

Thomas Gawne, Zhandos A Moldabekov, Oliver S Humphries +6

We compare the predictions of the dynamic structure factor (DSF) of ambient polycrystalline aluminium from time-dependent density functional theory (TDDFT) in the pair continuum re…

Strong geometry dependence of the X-ray Thomson Scattering Spectrum in single crystal silicon

Thomas Gawne, Zhandos A. Moldabekov, Oliver S. Humphries +17

We report on results from an experiment at the European XFEL where we measured the x-ray Thomson scattering (XRTS) spectrum of single crystal silicon with ultrahigh resolution. Com…

Nonlocal vs Local Pseudopotentials Affect Kinetic Energy Kernels in Orbital-Free DFT

Zhandos A. Moldabekov, Xuecheng Shao, Michele Pavanello +2

The kinetic energy (KE) kernel, which is defined as the second order functional derivative of the KE functional with respect to density, is the key ingredient to the construction o…

Accelerating Equilibration in First-Principles Molecular Dynamics with Orbital-Free Density Functional Theory

Lenz Fiedler, Zhandos A. Moldabekov, Xuecheng Shao +4

We introduce a practical hybrid approach that combines orbital-free density functional theory (DFT) with Kohn-Sham DFT for speeding up first-principles molecular dynamics simulatio…
