Comment on 'On a more exact treatment of the conduction-electron potential in first-principles calculations of lattice dynamics of metals'

Abstract

For original article see ibid., vol.6, p.L1 (1976). It is shown that the theory of Sun et al., though improved from the point of the core-eigenvalues, is still incorrect in treating electronic many-body effects. Moreover, the paper by Sun et al. contained misinterpretations of previous work, which are corrected.
