Density functional theory (DFT) is today a very powerful tool in the study of electronic structures of molecules. Advancements in DFT, in particular the development of Becke’s 3-parameter functional (B3LYP), together with the nearly exponential growth of computer power, have made it possible to treat ever larger systems at a reasonable level of accuracy. Density-functional theory (DFT) is a successful theory to calculate the electronic structure of atoms, molecules, and solids. Its goal is the quantitative understanding of material properties from the fundamental laws of quantum mechanics.
The week starts from an introduction to the many-body problem, and how things could be reformulated using the electron density. We will focus on observables, in particular those most directly related to the density. Finally we will discuss the Hohenberg-Kohn theorems. Density Functional Theory (DFT) has firmly established itself as the workhorse for atomic-level simulations of condensed phases, pure or composite materials and quantum chemical systems. This work offers a rigorous and detailed introduction to the foundations of this theory, up to and including such advanced topics as orbital-dependent functionals as well as both time-dependent and Introduction to Density Functional Theory Marie-Liesse Doublet Institut Charles Gerhardt, CNRS - Universit e Montpellier RS2E R eseau Stockage Electrochimique de l’Energie Marie-Liesse.Doublet@umontpellier.fr February 8, 2018 Marie-Liesse Doublet (ICGM) DFT February 8, 2018 1 / 32 A Brief History of Density Functional Theory Applied to Extracting Information from the Physical Adsorption Isotherm During the 1980s, considerable progress was made toward a theoretical understanding of fluid behavior in non-homogeneous systems. Particular interest was focused on phase changes in fluids constrained by the presence of walls, capillaries, and slits.
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.

We will focus on observables, in particular those most directly related to the density. Finally we will discuss the Hohenberg-Kohn theorems. Density Functional Theory is a rapidly developing branch of many-particle physics that has found applications in atomic, molecular, solid-state and nuclear physics.
