Abstract
The Lindemann equation was used to calculate the melting of metallic hydrogen. It is shown that, after transition from the molecular dielectric phase to the atomic metallic phase, hydrogen becomes a quantum liquid because of the atomic zero-point vibrations. The phase diagram of hydrogen is unique in that the molecular phase is the only solid phase of hydrogen.
