[Pw_forum] ecutvcut in Hybrid functionals

just set as default which is 0.0Ry. Could anyone explain why? For a typical semiconductor with s or p valence orbitals, what kind of ecutvcut value is recommended? Thanks a lot. best, Jianpeng Liu - Ph.D. candidate, Department of physics and astronomy, Rutgers

Dear QE users and developers, I wonder if hybrid functionals are implemented with fully-relativistic(frl) norm-conserving pseudopotentials(and also spin-orbital interaction and non-collinear magnetism). Thank you. best, Jianpeng Liu Graduate student, Department of Physics, Rutgers University

Hi Dmitry, I always did wannierisation after a nscf calculation before. I will follow your suggestion and try to do wanniersiation immediately after scf. Thanks a lot for your help. best, Jianpeng > Dear Jianpeng Liu, > I am not familiar with the hybrid functionals implementation in QE, &g
