Filling-driven Mott transition in SU(N) Hubbard models
Seung-Sup B. Lee, Jan von Delft, Andreas Weichselbaum
We study the filling-driven Mott transition involving the metallic and paramagnetic insulating phases in SU(N) Fermi-Hubbard models, using dynamical mean-field theory (DMFT) and th…

Generalized Schrieffer-Wolff transformation of multi-flavor Hubbard models
Seung-Sup B. Lee, Jan von Delft, Andreas Weichselbaum
We give a self-contained derivation of the low-energy effective interactions of the SU() Hubbard model, a multiflavor generalization of the one-band Hubbard model, by using a ge…
