[CPMD-list] USPP

[Dr. Balasubramanian Sundaram]

Hi All,

   We are trying to learn the ropes on the construction and usage of 
PPs. Specifically, we are interested in constructing the Vanderbilt
USPP to study CO_{2}, with the BLYP exchange/correlation functional.

   Can we mix the PPs of the elements? i.e., Can we use ultrasoft 
PPs (with BLYP) for oxygen, and C_MT_GIA_BLYP (that came with the CPMD 
PPLIB) for carbon?

  I realize that this question has some doubts on the USPP code as well,
but I do not know of any mailing list for that. Hope this cross-posting
in the cpmd-list is ok.

Thanks!

Bala
