Density Functional Theory. DFT started with the theorems of Hohenberg and Kohn (1964) demonstrating the equivalence of the polyelectronic wave function (complex number valued in the 6N-dimensional phase space for N electrons) and electronic density (real number valued in three-dimensional (3-D) ordinary space) for completely specifying the ground-state electronic structure and energy E0 of any Density Functional Theory Density-Functional Theory.

Density functional theory is derived from first principle method which uses electron density as main variable to solve n-electron problem [4]–[7]. In this method the 3n-dimensional equation (problem) is transferred to n separate 3-dimensional one. This theory suggests that, there is no individual electron. Density Functional Theory (DFT) has firmly established itself as the workhorse for the atomic-level simulation of condensed matter phases, pure or composite materials and quantum chemical systems.

Density-Functional Theory - Trygve Helgaker, Poul Jorgensen

Using the electron density significantly speeds up the calculation. Both density functional theory and Hartree–Fock theory are controlled through the SCF module, and the SCF Introduction section is also relevant here. Note Starting version 1.4 (tag v1.4a1 in the development repository), P SI 4 uses an updated and extended (to 104 elements) set of Bragg-Slater radii. Density functional theory (DFT) has been used in many fields of the physical sciences, but none so successfully as in the solid state. From its origins in condensed matter physics, it has expanded into materials science, high-pressure physics and mineralogy, solid-state chemistry and more, powering entire computational subdisciplines. Density-functional theory (DFT) is a computational quantum mechanical modelling method used in physics, chemistry and materials science to investigate the electronic structure (or nuclear structure) (principally the ground state) of many-body systems, in particular atoms, molecules, and the condensed phases. Density functional theory (DFT) is a type of electronic structure calculation that has rapidly gained popularity.

1.6 The Quantum Chemistry Tourist. 1.7 What Can't DFT Do?. 1.8 Density Functional Theory in Other Fields. 1.9 How To Approach This Book (Revisited). Density functional theory (DFT) is a quantum-mechanical (QM) method used in chemistry and physics to calculate the electronic structure of atoms, molecules and solids. It has been very popular in computational solid-state physics since the 1970s.
