Superconductivity in the recently proposed ground-state structures of atomic metallic hydrogen is investigated over the pressure range 500 GPa to 3:5 TPa. Near molecular dissociation, the electron{phonon coupling and renormalized Coulomb repulsion are similar to the molecular phase. A continuous increase in the critical temperature Tc with pressure is therefore expected, to 356K near 500 GPa. As the atomic phase stabilizes with increasing pressure, increases, causing Tc to approach 481K near 700 GPa. At the rst atomic{atomic structural phase transformation

The Properties of Hydrogen and Helium Under Extreme Conditions (2011, methodology): “The Cmcm structures is in fact analogous to the enthalpically-favored static-lattice structure R3m predicted by McMahon and Ceperley, 2011a at such pressures, but with a more efficient packing.”
