A density functional theory (DFT) that accounts for van der Waals (vdW) interactions in
condensed matter, materials physics, chemistry, and biology is reviewed. The insights that …

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 …

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 …

Hydrogen, the simplest and most abundant element in the Universe, develops a remarkably
complex behaviour upon compression. Since Wigner predicted the dissociation and …

Eighty years ago, it was proposed that solid hydrogen would become metallic at sufficiently
high density. Despite numerous investigations, this transition has not yet been …

Hydrogen is the most abundant element in the Universe. However, understanding the
properties of dense hydrogen is still an open challenge because—under megabar …

Quantum crystals abound in the whole range of solid-state species. Below a certain
threshold temperature the physical behavior of rare gases (He 4 and Ne), molecular solids …

The metallization of high-pressure hydrogen, together with the associated molecular to
atomic transition, is one of the most important problems in the field of high-pressure physics …

The insulator-metal transition in hydrogen is one of the most outstanding problems in
condensed-matter physics. The high-pressure metallic phase is now predicted to be liquid …
