Ab initio study of thermodynamically consistent physical properties of warm dense plasma

Thermodynamically consistent equation of state (EOS) of aluminum across a wide range of parameter space is investigated using density functional theory (DFT) based first-principles electronic structure methods. Our results can serve as a benchmark for developing new EOS models and database, and can be conveniently used for modeling important properties and processes of high energy density systems. The interesting electronic structure variations with the increasing electronic temperature are observed and will also be presented for discussion.
