D ec 1 99 9 FIRST - PRINCIPLES CALCULATIONS OF POSITRON ANNIHILATION IN SOLIDS
We present first-principles approaches based on density functional theory for calculating positron states and annihilation characteristics in condensed matter. The treatment of the electron-positron correlation effects (the enhancement of the electron density at the positron with respect to mean-field density) is shown to play a crucial role when calculating the annihilation rates. A generalize...

متن کاملFirst Principles Calculations
Calculations of the linestrengths and transition frequencies of the forbidden pure rotational spectrum of Hz in the vibrationally excited v2 state are presented. These transitions occur in the far-infrared region, and their observation may be complicated by vi u2 difference transitions. Examples of these are also given. Forbidden rovibrational transition frequencies and linestrengths have also ...
متن کاملExploiting periodic first-principles calculations in NMR spectroscopy of disordered solids.
Much of the information contained within solid-state nuclear magnetic resonance (NMR) spectra remains unexploited because of the challenges in obtaining high-resolution spectra and the difficulty in assigning those spectra. Recent advances that enable researchers to accurately and efficiently determine NMR parameters in periodic systems have revolutionized the application of density functional ...
متن کاملSpherical self-consistent atomic deformation model for first-principles energy calculations in ionic crystalline solids.
We present a first-principles method @called spherical self-consistent atomic deformation ~SSCAD!# for calculating the energy per unit cell in ionic crystalline solids. SSCAD is a density-functional method using the local-density approximation ~LDA!. Wave functions are localized about each ion, resulting in a single-particle Schrödinger’s equation for each ion. To simplify the calculation, we s...
