Communication: Shock adiabat of atomic nitrogen at megabar pressures

Abstract

We use spherical cellular method combined with a self-consistent density functional approach (quasizone method) to calculate the band structure and bulk properties of atomic nitrogen at megabar pressures and densities 3.2÷3.6 g/cm 3. Thermodynamic functions and shock adiabat calculated by this method correspond to recent measurements, showing a sharp increase in pressure along the shock adiabat in this range of densities. © 2012 American Institute of Physics.
