the type of pseudopotential problem

Post by yh0108 »

Dear users and developers:

According to the paper:EPW: A program for calculating the electron-phonon coupling using maximally localized Wannier functions,
it said that we can use norm-conserving or ultrasoft pseudopotential,
my question is that does EPW support the PAW or other type of pseudopotential?
Thank you in advance!

Dear Yao-Hong,

EPW v4 (to be released 29 Apr) supports norm-conserving pseudos.
The infrastructure for US pseudos is in place but is not tested yet.
PAW potentials are not supported.

Hi,

Why is it commented in the ephwann_shuffle.f90 that "No ultrasoft now", even in the latest version!

Hi,

The US part has not been tested.
