    "abstract": "We present a new Monte Carlo method which couples Path Integral for finite\ntemperature protons with Quantum Monte Carlo for ground state electrons, and we\napply it to metallic hydrogen for pressures beyond molecular dissociation. We\nreport data for the equation of state for temperatures across the melting of\nthe proton crystal. Our data exhibit more structure and higher melting\ntemperatures of the proton crystal than Car-Parrinello Molecular Dynamics\nresults. This method fills the gap between high temperature electron-proton\nPath Integral and ground state Diffusion Monte Carlo methods.",
