The density functional theory (DFT) treats the electron density as the central variable rather than the many-body wavefunction. This conceptual difference leads to a remarkable reduction in difficulty: the density is a function of three variables, i.e.the three Cartesian directions, rather than variables as the full many-body wavefunction is. functional theory (DFT) has become the most popular one. The number of works about the implemen- tation of DFT or using the DFT as a computational scheme is continuously increasing.

3 Feb 2021 Density Functional Theory Calculations. Edited by: Sergio Ricardo De Lazaro, Luis Henrique Da Silveira Lacerda and Renan Augusto Pontes Density functional theory is a formally exact description of a many-body quantum system through the density alone. In practice, approximations are necessary.
