The one-dimensional Bose-Fermi-Hubbard model in the limit of fast fermions
Alexander Mering, Michael Fleischhauer
We discuss the ground-state phase diagram of the one-dimensional Bose-Fermi-Hubbard model (BFHM) in the limit of fast fermions based on an effective boson model. We give a detailed…

The one-dimensional Bose-Fermi-Hubbard model in the ultrafast-fermion limit: Charge density wave phase and MI - CDW phase separation
Alexander Mering
In a recent work [1] we presented results for the Bose-Fermi-Hubbard model (BFHM) in the limit of ultrafast fermions. The present work gives an overview over the used methods and a…

Multi-band and nonlinear hopping corrections to the 3D Bose-Fermi Hubbard model
Alexander Mering, Michael Fleischhauer
Recent experiments revealed the importance of higher-band effects for the Mott insulator (MI) -- superfluid transition (SF) of ultracold bosonic atoms or mixtures of bosons and fer…
