Energy functionals serve as the basis for different models and methods in quantum and
classical many-particle physics. Arguably, one of the most successful and widely used …

Accurate knowledge of the properties of hydrogen at high compression is crucial for
astrophysics (eg, planetary and stellar interiors, brown dwarfs, atmosphere of compact stars) …

Warm dense matter (WDM)—an exotic state of highly compressed matter—has attracted
increased interest in recent years in astrophysics and for dense laboratory systems. At the …

Matter at extreme temperatures and pressures—commonly known as warm dense matter
(WDM)—is ubiquitous throughout our Universe and occurs in astrophysical objects such as …

Simulations of finite temperature quantum systems provide imaginary frequency Green's
functions that correspond one to one to experimentally measurable real-frequency spectral …

We present a methodology for the linear-response time-dependent density functional theory
(LR-TDDFT) calculation of the dynamic density response function of warm dense matter in …

Rigorous diagnostics of experiments with warm dense matter are notoriously difficult. A key
method is X-ray Thomson scattering (XRTS), but the interpretation of XRTS measurements is …

The electronic exchange─ correlation (XC) kernel constitutes a fundamental input for the
estimation of a gamut of properties such as the dielectric characteristics, the thermal and …

The study of matter under extreme densities and temperatures as they occur, for example, in
astrophysical objects and nuclear fusion applications has emerged as one of the most active …

We present an effective static approximation (ESA) to the local field correction (LFC) of the
electron gas that enables highly accurate calculations of electronic properties like the …
