Active research is ongoing that investigates the properties of matter under extreme pressure.
Such condensed matter is found inside planets at millions of atmospheres and thousands of …

Motivated by the current high interest in the field of warm dense matter research, in this
article we review the uniform electron gas (UEG) at finite temperature and over a broad …

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 …

Carbon is an element with extremely versatile bonding properties and theoretical
calculations have suggested the possible existence of several hundred structural allotropes …

The effects of hydrocarbon reactions and diamond precipitation on the internal structure and
evolution of icy giant planets such as Neptune and Uranus have been discussed for more …

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 …

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 …

This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The
aim is to provide newcomers to the area with insights into: the basic physics of FELs, the …

ELI-Beamlines (ELI-BL), one of the three pillars of the Extreme Light Infrastructure
endeavour, will be in a unique position to perform research in high-energy-density-physics …

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 …
