Density functional taking into account nuclear thermal motion of compressed matter

Bogolyubov's inequality is used to generalize the density functional method to take into account nuclear thermal motion. The results apply to a two-component system in which the nuclei satisfy classical statistics. Applications to a cell model describing dense heated states of matter are considered.All-Union Research Institute of Opticophysical Measurements of the USSR State Standards.
