Density functional theory in materials science - PubMed
WebMay 16, 2024 · Within the field of computational materials science, such abundance of data is possible mainly due to the success of density functional theory (DFT) and the fast development of computational capabilities. On the other hand, advances in instrumentation and electronics have enabled experiments to produce large quantities of results. … 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 … See more In the context of computational materials science, ab initio (from first principles) DFT calculations allow the prediction and calculation of material behavior on the basis of quantum mechanical considerations, … See more As usual in many-body electronic structure calculations, the nuclei of the treated molecules or clusters are seen as fixed (the Born–Oppenheimer approximation), generating a static external potential V, in which the electrons are moving. A stationary electronic state See more The DFT formalism described above breaks down, to various degrees, in the presence of a vector potential, i.e. a magnetic field. In such a situation, the one-to-one mapping between the ground-state electron density and wavefunction is lost. … See more The predecessor to density functional theory was the Thomas–Fermi model, developed independently by both Llewellyn Thomas and Enrico Fermi in 1927. They used a statistical … See more The same theorems can be proven in the case of relativistic electrons, thereby providing generalization of DFT for the relativistic case. Unlike the nonrelativistic theory, in the … See more The major problem with DFT is that the exact functionals for exchange and correlation are not known, except for the free-electron gas. … See more In general, density functional theory finds increasingly broad application in chemistry and materials science for the interpretation and prediction of … See more slow dancing aly \\u0026 aj lyrics
