Dear QE users, I hope this message finds you well. I am looking for a pseudopotential for the rare earth element Erbium, which includes a fully relativistic correction, to be able to do spin-orbit coupling calculations for Er-4f orbital using the Quantum Espresso package. Actually, pure DFT and even HSE methods don't remove the degeneracy of Er-4f orbitals. I would appreciate any suggestions/help. Thank you. Kind regards, Alireza Shabani Postdoc researcher, Denmark Technical University Copenhagen, Denmark
