Pseudopotential questions

Hi,

I’ve been trying to reproduce MP total energies, and I just wanted to ask about the pseudopotential versions I’m supposed to use. Attached is a table summarizing the reported MP total energies and my calculation using MP reported input files. I’ve been using PAW POTCAR files: PBE version 54.

Here’s the list of PPs I have access to and I just wanted to ask which is the one MP uses:

  • PAW POTCAR files: PBE version 64
  • PAW POTCAR files: PBE version 54
  • PAW POTCAR files: PBE version 52
  • PAW POTCAR files: LDA & PW91 & PBE
mp-id Etot_MP (eV/atom) Etot_recalc (eV/atom) diff (eV/atom)

Thanks!

Hi @Suxuen_Yew, take a look at this post. The older PBE GGA/GGA+U calculations use 2010 and earlier POTCARs. The r2SCAN calculations currently use this set of 54 POTCARs

The 54 POTCARs will make your results compatible with the r2SCAN data we currently have. The
