[Pw_forum] the charge of the individual atom

[lfhuang]

Dear W. Fang:
    You can run the excutable "projwfc.x" to get the charge of an individual atom. Note: it is not the Mulliken population analysis, but the Lowdin population analysis. The former takes  accounts the overlaps between orbitals, while the latter not and a spilling factor is used to judge the contribution of the omitting term. Despite this difference, these two population analyses can both precisely tell the physics behind in vast cases.
   You can read the INPUT file for the "projwfc.x" and the text on the head of projwfc.f90 for details.

Best Wishes!

Yours Sincerely
L. F. Huang
