    Abstract
  • Based on Liberman's statistical self-consistent field INFERNO mode, we calculated the equation of sate (EOS) and the Hugoniot of gold (Au) in a wide range of temperatures and densities. The electronic part of the EOS for Au was obtained by solving the self-consistent field Dirac equation at each density and temperature. In the same way, the 300 K isotherm of gold was obtained by modifying the Virial pressure and the ion part of the EOS was calculated by the free volume model. The cold pressure and Hugoniot were compared with the experimental data and other theoretical methods with the most satisfactory achieved. Our study shows that Liberman's INFERNO model can be used to calculate the EOS for gold in a wide range of temperatures and densities.
