## Structures and optical properties of solid hydrogen at ultrahigh pressures
Division of Materials Physics, Graduate School of Engineering Science, Osaka University Toyonaka, Osaka 560-8531, Japan
We have studied the electronic energy bands for the structures whose primitive cell contains up to four molecules, with full optimization of the structures, based on the GGA and LDA band calculations.
Above 250 GPa, the eventual optimal structure obtained by the GGA or the LDA calculation is PACS:62.50.+p - High-pressure and shock wave effects in solids and liquids (for high pressure apparatus and techniques, see 07.35.+k; for shock wave initiated high-pressure chemistry, see 82.40.Fp; for high-pressure behavior of rocks and minerals, see 91.60.Gf; see also 61.50.Ah - Theory of crystal structure, crystal symmetry; calculations and modeling 71.30.+h - Metal-insulator transitions and other electronic transitions |
