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 …

Hydrogen, the first element in the periodic table, is predicted to become metallic at extremely
high‐pressure conditions. Solid metallic hydrogen is believed to possess extraordinary …

The theoretical exploration of the phase diagrams of binary hydrides under pressure using
ab initio crystal structure prediction techniques coupled with first principles calculations has …

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 …

A theoretical study is reported of the molecular-to-atomic transition in solid hydrogen at high
pressure. We use the diffusion quantum Monte Carlo method to calculate the static lattice …

Experimental studies of compressed matter are now routinely conducted at pressures
exceeding 1 mln atm (100 GPa) and occasionally at pressures greater than 10 mln atm (1 …

Establishing the phase diagram of hydrogen is a major challenge for experimental and
theoretical physics. Experiment alone cannot establish the atomic structure of solid …

A new phase V of hydrogen was recently claimed in experiments above 325 GPa and 300 K.
Because of the extremely small sample size at such record pressures the measurements …

The computational and experimental exploration of the phase diagrams of binary hydrides
under high pressure has uncovered phases with novel stoichiometries and structures, some …

At high pressure, the typical behavior of elements dictated by the periodic table—including
oxidation numbers, stoichiometries in compounds, and reactivity, to name but a few—is …
