Pressure and temperature influence all properties of a chemical system. And determine the
fate of a chemical reaction. Gases—and phase and chemical equilibria involving gaseous …

Prediction of stable crystal structures at given pressure-temperature conditions, based only
on the knowledge of the chemical composition, is a central problem of condensed matter …

We have developed an efficient and reliable methodology for crystal structure prediction,
merging ab initio total-energy calculations and a specifically devised evolutionary algorithm …

The sources and evolutionary histories of volatile elements in primitive meteorites and
planetary atmospheres are classic unsolved problems in the planetary sciences. Signatures …

In this critical review I describe fascinating experimental and theoretical advances in 'noble
gas' chemistry during the last twenty years, and have taken a somewhat unexpected course …

M atter in bulk has both a microscopic and macroscopic description, with the latter going
back to the very earliest days of thermodynamics. Of the common thermodynamic variables …

Solid hydrogen, an electrical insulator, is predicted to become an alkali metal under extreme
compression, although controversy surrounds the pressure required to achieve this,,. The …

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 …

Recent advances in high-pressure technologies and large-scale experimental and
computational facilities have enabled scientists, at an unprecedented rate, to discover and …

Plasmas occur in a wide range of the density-temperature plane. The physical quantities can
be expressed by Green's functions which are evaluated by means of standard quantum …
