Electron-ion pseudopotentials in metals☆
Abstract Pseudopotential form-factors for Al, Pb, Na and K are plotted for a simple model potential which is justified in the text. They are in good agreement with potentials of Heine and Abarenkov.

A little bit of lithium does a lot for hydrogen
From detailed assessments of electronic structure, we find that a combination of significantly quantal elements, six of seven atoms being hydrogen, becomes a stable metal at a pressure approximatelyExpand

Atomic and Ionic Radii of Elements 1-96.
Atomic and cationic radii have been calculated for the first 96 elements, together with selected anionic radii. The metric adopted is the average distance from the nucleus where the electron densityExpand

Benzene under high pressure: a story of molecular crystals transforming to saturated networks, with a possible intermediate metallic phase.
In a theoretical study, benzene is compressed up to 300 GPa. The transformations found between molecular phases generally match the experimental findings in the moderate pressure regime (<20 GPa):Expand

Structure and bandgap closure in dense hydrogen
The possibility that steadily compressed hydrogen might undergo a transition from a proton-paired insulator to a monatomic metal was first suggested in 1935 (ref. 1). But experimental realization ofExpand

The unusual and the expected in the Si/C phase diagram.
In the Si/C phase diagram, the only stable phases at P = 1 atm are the numerous polytypes of the simplest 1:1 stoichiometry, SiC. However, many metastable yet likely to be kinetically persistentExpand

Pairing in dense lithium
The light alkali metals have played an important role in the developing understanding of the electronic structure of simple metals. These systems are commonly viewed in terms of an underlyingExpand
