Application of Coherent-Potential Approximation to Disordered Muffin-Tin Alloys

I report implementation of the coherent-potential approximation for obtaining the electronic density of states and component charge densities in disordered muffin-tin alloys. Illustrative results for ${\mathrm{Cu}}_x{\mathrm{Ni}}_{1-x}$ are presented. The extent to which the self-consistency in treating disorder influences the electronic spectrum is considered.
