Abstract
Functional integrals and the notion of Legendre transformation are used to formulate the average-atom model and the density-functional theory in the same formalism, stressing their common theoretical basis. Particularly, the Kohn and Sham equations are proven to appear naturally by performing a saddle-point evaluation of a specific functional integral. Exact expressions for the exchange-correlation terms in the grand potential at finite temperature are derived.
