Equivalence of Gutzwiller and slave-boson mean-field theories for multi-band Hubbard models

Abstract

We demonstrate that a recently introduced slave-boson mean-field theory is equivalent to our Gutzwiller theory for multi-band Hubbard models with general onsite interactions. We relate the different objects that appear in both approaches at zero temperature and discuss the limitations of both methods.
