The many-body problem in a hot dense plasma is treated using the effective one-particle description of density-functional theory. Three key ideas emerge, viz., (i) the neutral-pseudoatom (NPA) concept to describe a nucleus plus its electron distribution in the plasma, (ii) the concept of hopping electrons describing the effect of the ion-distribution on the electrons, which are shown to exist as bound, hopping, and free electrons, and (iii) the concept of the mobility edge replacing that of the continuum edge as we go to denser plasmas
