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…

Hybridisation in two-band Hubbard models with different bandwidths
Joerg Buenemann, David Rasch, Florian Gebhard
We investigate the orbital selective Mott transition in two-band Hubbard models by means of the Gutzwiller variational theory. In particular, we study the influence of a finite loc…
