Ab initio equation of state of hydrogen for inertial fusion applications

ORAL

Abstract

We describe {\it ab initio} electronic structure calculations (DFT molecular dynamics and quantum Monte Carlo) of the equation of state of hydrogen in a regime relevant for ICF applications. We find the computed EOS to be quite close to that of the most recent SESAME table (constructed by G. Kerley, 2004). A simple density-dependent correction brings the recent SESAME EOS into nearly perfect agreement with ours in the chosen region. Simulations of ICF applications with this {\it corrected} SESAME table are discussed.
