Residual resistivity of vacancies in simple metals

The residual resistivities of vacancies in simple metals are estimated by using the Kohn-Sham method to calculate a self-consistent scattering potential for free electrons. The results are compared to other calculations and experimental resistivities.     

Stable minimum space partitioning in linear time

In the stable0–1 sorting problem the task is to sort an array ofn elements with two distinct values such that equal elements retain their relative input order. Recently, Munro, Raman and Salowe gave an algorithm which solves this problem inO(n log*n) time and constant extra space. We show that by a modification of their method the stable0–1 sorting is possible inO(n) time andO(1) extra space. Stable three-way partitioning can be reduced to stable0–1 sorting. This immediately yields a stable minimum space quicksort, which sorts multisets in asymptotically optimal time with high probability.

Spherical solid model for muon screening in metals

The spherical solid model of Almbladh and von Barth is applied to muon screening in simple and noble metals. The spherical average of the host pseudoion potential around the impurity is incorporated in the density functional calculations, which have been carried out self-consistently for both paramagnetic and spin-polarized Al, Na and Cu. It is found essential to use the spin-polarized form to evaluate the Knight shift at low metallic densities. Results are obtained for the muon hyperfine field, electric field gradient, heat of solution and diffusion barrier at different lattice locations.
