Comment on ''All-electron and pseudopotential force calculations using the linearized-augmented-plane-wave method''

Abstract

We show that the atomic force formula of Yu, Singh, and Krakauer [Phys. Rev. B 43, 6411 (1991)] for the linearized-augmented-plane-wave method is equivalent to that previously found by us. In particular, a kinetic muffin-tin-surface contribution described by Yu, Singh, and Krakauer is shown to be also included in our formula. © 1993 The American Physical Society.
