Abstract
A density functional method, which represents the total charge density as a sum of self-consistently determined localized densities, is described. While this approach is generally less accurate than conventional band-structure methods, it offers a relatively simple interpretation of polarization and related properties. The method is illustrated with results for NaCl, MgO, and AlP.
