[Pw_forum] Need Pseudo potentials

2011-02-16 Thread priyanka goud
Dear PWSCF users,

I need pseudo potentials for Rb(
Rubidium)  metal.
I have gone through this website
(http://www.quantum-espresso.org/pseudo.php) for the same.
 But there are some elements(eg:Rb,Fr etc) for which pseudo potentials
has not been defined.

Is there any way to retrieve pseudo potentials for such elements(My
case is Rubidium-Rb).

Thanks in Advance.

Dear Priyanka,


there are a few projects that make their pseudopotentials
available - if you go to
http://quantum-espresso.org/pseudo.php
and click on the left ("Notes") you'll see the links.

The Fritz-Haber package, in particular, has a Troullier-Martin
pseudopotential for Rubidium, that could be converted into UPF
using the converter fhi2upf (in upftools).

Once you have generated/converted the pseudo, test it. Does the
atom come out with PWSCF as it does in the pseudo code (same
pseudoeigenvalues, once you take into account that the zero
of energy is different)? Are there other calculations you can compare
yourself to?
