Generalized Local Density Approximation Uniform Electron Gases . II . The Generalized Local Density Approximation in One Dimension
We introduce a generalization (gLDA) of the traditional Local Density Approximation (LDA) within density functional theory. The gLDA uses both the one-electron Seitz radius rs and a two-electron hole curvature parameter η at each point in space. The gLDA reduces to the LDA when applied to the infinite homogeneous electron gas but, unlike the LDA, is is also exact for finite uniform electron gas...
متن کاملCorrecting overbinding in local-density-approximation calculations
We introduce a semiempirical method to correct the systematic equilibrium lattice parameters underestimation present in first principles calculations based on the local density approximation. The method consists in performing calculations under a negative pressure such that the calculated equilibrium volume matches the experimentally observed one. We find that elastic properties obtained under ...
متن کاملDiffusion-limited reactions in crowded environments: a local density approximation.
In the real world, diffusion-limited reactions in chemistry and biology mostly occur in crowded environments, such as macromolecular complex formation in the cell. Despite the paramount importance of such phenomena, theoretical approaches still mainly rely on the Smoluchowski theory, only valid in the infinite dilution limit. In this paper we introduce a novel theoretical framework to describe ...
متن کاملLocal Density Approximation Method for Correlated Metals
While the Local Density Approximation LDA+U method is well established for Mott insualtors with well localized orbitals, its application to weakly correlated metals is questionable. By extending the Stoner approach to LDA+U, we show that LDA+U enhances the Stoner factor, while reducing the density of states. The most important correlation effects in metals, fluctuation induced mass renormalizat...
متن کاملLocal Density Approximation for Pairing Correlations in Nuclei
We introduce a natural and simple to implement renormalization scheme of the Hartree–Fock–Bogoliubov (HFB) equations for the case of zero range pairing interaction. This renormalization scheme proves to be equivalent to a simple energy cut–off with a position or density dependent running coupling constant. Subsequently, we present self–consistent HFB calculations with a full consideration of th...
