Query: Mean-field potential calculations of high-pressure equation of state for
  shock-compressed BeO   A systematic study of the Hugoniot equation of state, phase transition, and
the other thermodynamic properties including the Hugoniot temperature, the
electronic and ionic heat capacities, and the Gr\"{u}neisen parameter for
shock-compressed BeO, is presented by calculating the total free energy. The
method of calculations combines first-principles treatment for 0-K and finite-T
electronic contribution and the mean-field-potential approach for the
vibrational contribution of the lattice ion to the total energy. Our calculated
Hugoniot shows good agreement with the experimental data.
