DFPT with DFT+U

Post by yjzhou » Tue Jul 03, 2012 8:04 pm

Hi all,
Is it possible to do phonon dispersion calculations with DFPT in the regime of DFT+U in the current version of ABINIT?

Thanks,
Yuanjun

Hi!

i think that it is still not possible to do that (or, developers, am I wrong?). But you have it in QE package for certain pseudopotentials.

Hi Igor,
As far as I know QE cannot do this using PAW potentials. But it seems that there is no requirement on PAW potential when applying DFT+U
in QE. Am I right?

Yes, you are. But I'm not 100% sure of this, since I don't use QE.
