Abstract
We present a density functional theory for hot dense plasmas, applicable to high Z atom, where electronic structure of atom as microscopic aspect and ionic distribution as macroscopic aspect are determined self-consistently. In this theory, the plasma is regarded as an ensemble of the virtual \lq neutral atom' or, in other words, pseudo neutral atom. We apply our theory to Fe plasmas at temperatures T=100, eV and 1, keV in the density range 0.1ρ solid-- 200ρ solid (ρ solid=8.465× 1022, cm-3), neglecting the polarization of continuum electrons, and consequently obtain the result that the interatomic effective potential is almost the same as the bare-Coulomb type potential in one-component plasmas (OCP). From the obtained profile of the potential veff(r) which determines bound electron states, we suggest a possibility of resonance states. The obtained internal energy for ion subsystem is lower than the Monte Carlo result for OCP, but the difference is within a few percent.
