Abstract
Density-functional theory and molecular dynamics is used to simulate dense metallic liquid hydrogen at a temperature of 500 K and over the pressure range 386.8(4)- 883.7(3) GPa. The superconducting transition temperature of the liquid is calculated to be 308(6) K at 386.8 GPa and increasing to a maximum of 372(2) K at 783.7(4) GPa. The melting line of hydrogen decreases with pressure in this pressure range. The melting temperature is 291 K at 400 GPa. Given that the calculated critical temperature is above the melting temperature, it is concluded that hydrogen will be a liquid superconductor at room temperature and at high pressures.
