Equivalence of Gutzwiller and slave-boson mean-field theories for multi-band Hubbard models
Joerg Buenemann, Florian Gebhard
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 re…

On the way to a Gutzwiller density functional theory
W. Weber, J. Buenemann, F. Gebhard
Multi-band Gutzwiller-correlated wave functions reconcile the contrasting concepts of itinerant band electrons versus electrons localized in partially filled atomic shells. The exa…
