Journal ArticleDOI
Improved tetrahedron method for Brillouin-zone integrations
TL;DR: In this article, the tetrahedron method was used for Brillouin-zone integrations and a translational grid of k points and tetrahedral elements was proposed to obtain results for insulators identical to those obtained with special-point methods with the same number of points.
Journal ArticleDOI
Band theory and Mott insulators: Hubbard U instead of Stoner I.
TL;DR: A form for the exchange-correlation potential in local-density band theory, appropriate for Mott insulators, and finds that all late-3d-transition-metal monoxides, as well as the parent compounds of the high-${\mathit{T}$ compounds, are large-gap magnetic insulators of the charge-transfer type.
Journal ArticleDOI
Explicit, First-Principles Tight-Binding Theory
Ole Krogh Andersen,Ove Jepsen +1 more
TL;DR: In this paper, the minimal base of muffin-tin orbitals is transformed exactly into a tight-binding base and the linear transformations, the orbitals, and the Hamiltonian overlap are expressed in terms of one matrix, the canonical structure matrix.
Journal ArticleDOI
Electron Localization in Solid-State Structures of the Elements: the Diamond Structure
Andreas Savin,Ove Jepsen,J. Flad,Ole Krogh Andersen,Heinzwerner Preuss,Hans Georg von Schnering +5 more
TL;DR: In this paper, the electron localization function (ELF) was introduced as a measure of the probability of finding an electron in the neighborhood of another electron with the same spin, and it was shown that the region between the two C atoms does have a high ELF value.
Journal ArticleDOI
Illustration of the linear-muffin-tin-orbital tight-binding representation: Compact orbitals and charge density in Si
TL;DR: In this article, the authors derived the tight-binding (TB) orbitals by exact transformation of the conventional set of linear muffin-tin orbitals (LMTO's) for crystalline silicon.
