Density functional theory as thermodynamics

摘要: Thermodynamical interpretation of the density functional theory is developed for an electronic ground state, with particular emphasis on fact that when system not homogeneous kinetic energy varies from point to point. Local thermodynamical quantities, temperature, free energy, and entropy, are defined. The formalism yields same Sackur-Tetrode expression local entropy earlier obtained by other methods, plus corrections equation “nonideality’. Various aspects description discussed.
