Hohenberg–kohn theorems
Nettet29. jun. 2024 · The Hohenberg-Kohn theorem does not only apply to nuclear Coulomb potentials, but also to non-nuclear and/or non-Coulomb potentials. For example, if you have a molecule in a possibly non-uniform external electric field, then one can reveal the exact distribution of the electric field simply by examining the ground state density of … NettetPHYSICAL REVIEW VOLUM E 136, NUM B ER 3 8 9 NOVEMEBR 1964 InhOmOgeIIeouS EleCtrOn Gaa* P.

Theorem 1. The external potential (and hence the total energy), is a unique functional of the electron density. If two systems of electrons, one trapped in a potential $${\displaystyle … Se mer 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) … Se mer 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 … Se mer 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 … Se mer 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 … Se mer 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 Se mer The major problem with DFT is that the exact functionals for exchange and correlation are not known, except for the free-electron gas. However, approximations exist which permit the calculation of certain physical quantities quite accurately. One … Se mer In general, density functional theory finds increasingly broad application in chemistry and materials science for the interpretation and prediction of complex system behavior at an atomic scale. Specifically, DFT computational methods are applied for synthesis-related … Se mer
