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

Recently, static pressures of more than 1.0 TPa have been reported, which raises the
question: what is the maximum static pressure that can be achieved using diamond anvil cell …

Under pressure, metals exhibit increasingly shorter interatomic distances. Intuitively, this
response is expected to be accompanied by an increase in the widths of the valence and …

The properties of all materials at one atmosphere of pressure are controlled by the
configurations of their valence electrons. At extreme pressures, neighboring atoms approach …

An interatomic potential for high-pressure high-temperature (HPHT) crystalline and liquid
phases of sodium is created using a neural-network (NN) representation of the ab initio …

Sodium exhibits a pronounced minimum of the melting temperature at∼ 118 gigapascals
and 300 kelvin. Using single-crystal high-pressure diffraction techniques, we found that the …

Ab initio random structure searching and single-crystal x-ray diffraction have been used to
determine the full structures of three phases of lithium, recently discovered at low …

Alkali metals exhibit unexpected structures and electronic behavior at high pressures.
Compression of metallic sodium (Na) to 200 GPa leads to the stability of a wide-band-gap …

Crystal structure determination at extreme pressures is currently possible at synchrotron
beamlines optimized for such a purpose. We report the description of the experimental setup …

Methods for and the results of the computer simulation of liquid metals are reviewed. Two
basic methods, classical molecular dynamics with known interparticle potentials and the ab …
