Pressure is a fundamental thermodynamic variable that can be used to control the properties
of materials, because it reduces interatomic distances and profoundly modifies electronic …

Pressure profoundly alters all states of matter. The symbiotic development of ultrahigh-
pressure diamond anvil cells, to compress samples to sustainable multi-megabar pressures; …

In stark contrast to common ice, I h, water ice at planetary interior conditions has been
predicted to become superionic with fast-diffusing (that is, liquid-like) hydrogen ions moving …

Ab initio molecular dynamics revolutionized the field of realistic computer simulation of
complex molecular systems and processes, including chemical reactions, by unifying …

Hydrogen bonds profoundly influence the fundamental chemical, physical and biological
properties of molecules and materials. Owing to their relatively weaker interactions …

We use new interior models of cold planets to investigate the mass-radius relationships of
solid exoplanets, considering planets made primarily of iron, silicates, water, and carbon …

Recent developments in path integral methodology have significantly reduced the
computational expense of including quantum mechanical effects in the nuclear motion in ab …

In the phase diagram of water, superionic ices with highly mobile protons within the stable
oxygen sublattice have been predicted at high pressures. However, the existence of …

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 …

Superionic states are phases of matter that can simultaneously exhibit some of the
properties of a liquid and of a solid. For example, in superionic ice, hydrogen atoms can …
