Plasmonic phenomena in metals are commonly explored within the framework of classical
electrodynamics and semiclassical models for the interactions of light with free-electron …

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 …

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 …

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 …

Hydrogen at extreme temperatures and pressures is of key relevance for cutting-edge
technological applications, with inertial confinement fusion research being a prime example …

The accurate description of electrons at extreme density and temperature is of paramount
importance for, eg, the understanding of astrophysical objects and inertial confinement …

Coupling between light and material excitations underlies a wide range of optical
