High-concentration extension of the Friedel sum rule and application to the coherent potential approximation

Abstract
The classical Friedel sum rule has been extended to the high-concentration region and the self-consistency condition so obtained has been applied to the coherent potential approximation. It is shown that the present approach is useful in realistic calculations for obtaining a condition for the self-consistent potential, which cannot under any conditions be independent of composition.File in questo prodotto:
