Pseudopotentials

I am repeating the calculations on this paper:Raman scattering intensities in BaTiO3 and PbTiO3 prototypical ferroelectrics from density functional theory. Highly transferable Teter pseudopotentials were Mentioned in the literature,But in my bag some pseudopotential I do not know how to choose and c...

Re: DFPT [SOLVED]

Hello. Thank you very much for your reply. I really count the ion system. I am repeating the literature to calculate the phonon spectrum of barium titanate. There is a split in the literature, I think it should be a parameter to split
