Designing materials with advanced functionalities is the main focus of contemporary solid-
state physics and chemistry. Research efforts worldwide are funneled into a few high-end …

Two hydrogen-rich materials, H 3 S and LaH 10, synthesized at megabar pressures, have
revolutionized the field of condensed matter physics providing the first glimpse to the …

One of the long-standing challenges in experimental physics is the observation of room-
temperature superconductivity 1, 2. Recently, high-temperature conventional …

The recent observation of room-temperature superconductivity will undoubtedly lead to a
surge in the discovery of new, dense, hydrogen-rich materials. The rare earth metal …

Producing metallic hydrogen has been a great challenge in condensed matter physics.
Metallic hydrogen may be a room-temperature superconductor and metastable when the …

Pressure has long been recognized as a fundamental thermodynamic variable but its
application was previously limited by the available pressure vessels and probes. The …

Two or more liquid states may exist even for single-component substances, which is known
as liquid polymorphism, and the transition between them is called liquid–liquid transition …

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

Dense fluid metallic hydrogen occupies the interiors of Jupiter, Saturn, and many extrasolar
planets, where pressures reach millions of atmospheres. Planetary structure models must …

Fluid polyamorphism is the existence of different condensed amorphous states in a single-
component fluid. It is either found or predicted, usually at extreme conditions, for a broad …
