The f-electron challenge: localized and itinerant states in lanthanide oxides united by GW@LDA+U

Hong Jiang, Ricardo I. Gomez-Abal, Patrick Rinke +1

Many-body perturbation theory in the GW approach is applied to lanthanide oxides, using the local-density approximation plus a Hubbard U correction (LDA+U) as the starting point. G…
