Abstract
Superconductivity in the recently proposed ground-state structures of atomic metallic hydrogen is calculated over the pressure range 500 GPa to TPa. Near molecular dissociation, the electron-phonon coupling and renormalized Coulomb repulsion are similar to the molecular phase. A nearly continuous increase in the critical temperature with pressure is thus predicted in this range, to K near 500 GPa. As the atomic phase stabilizes with increasing pressure, increases, causing to approach 481 K near 700 GPa. At the first atomic-atomic structural phase transformation near 1– TPa, a discontinuous jump in occurs, causing to increase up to 764 K.
