Effects of Coulomb and Fermi corrections on the equation of state of dense plasmas

POSTER

Abstract

In this presentation, we derive corrections for two frequently neglected or poorly approximated components of the equation of state for dense plasmas: (i) the Coulomb correction, which accounts for electron-electron interactions and (ii) the Fermi correction, which accounts for (frequently important) quantum-mechanical behavior of electrons. We demonstrate a more accurate approach to these calculations and discuss their effects on thermodynamic properties, ionization, and emissivity of dense plasmas.
