Foundations of Density Functional Theory: Existence Theorems,The starting point of any discussion of DFT is the Hohenberg-Kohn (HK) theorem [6]. It represents the most basic of a number of existence theorems which ensure that stationary many-particle systems can be characterized (fully) by the ground state density and closely related quantities.

Effective Single-Particle Equations,Let us return to the simplest situation considered so far, i.e. to a Hamiltonian of type (2.1) with a non-degenerate ground state. For this system the Hohenberg-Kohn theorem states that knowledge of the ground state density is sufficient to determine all ground state observables.

Virial Theorems,Virial theorems are derived by considering the behavior of all relevant quantities

Time-Dependent Density Functional Theory,Time-dependent density functional theory (TDDFT) has developed rapidly since its beginnings in 1984 [472, 473].

Relativistic Density Functional Theory,Given the success of nonrelativistic DFT, the question concerning a suitable relativistic extension arises quite naturally.
