[QE-users] Fwd: Hydrogen atom pseudopotential files with q=1.5e and q=0.75e (PBE, USPP)

[Nicola Marzari]

Dear Gökhan,


as far as I know there is a legacy table of old pseudopotentials:
http://pseudopotentials.quantum-espresso.org/legacy_tables/original-qe-pp-library

It's not recommended in general, but for H you can find some old Von 
Barth Car pseudos with fractional charges (maybe good to test these to 
make sure they give reasonable results).

Another very precious pseudo there is the pure Coulombic one:
H.coulomb-ae.UPF

Again, to be checked, but I believe that just chaning Zval you can also 
use it as a Cooulomb pseudo for heavier atoms, e.g. the second row from 
Li onwards, that can be useful to do all-electron tests with QE (mind 
you, for second row you easily need 1000 Ry of ecutrho).

Any comments on this actually much appreciated,
