摘要：

A method for efficient solution of the Kohn-Sham equations, the central equations of density-functional electronic structure calculations, is presented. It combines the simplicity of the damped gradient iteration with the efficiency of multigrid techniques. The long-standing problem of calculating the optimized effective potential of Kohn-Sham theory for orbital density functionals has been solved with this algorithm. (C) 2004 Elsevier Inc.
