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…
Analytic approximations to the phase diagram of the Jaynes-Cummings-Hubbard model with application to ion chains
Alexander Mering, Peter A. Ivanov, Kilian Singer +1
We discuss analytic approximations to the ground state phase diagram of the homogeneous Jaynes-Cummings-Hubbard (JCH) Hamiltonian with general short-range hopping. The JCH model de…
Fermion mediated long-range interactions of bosons in the 1D Bose-Fermi-Hubbard model
Alexander Mering, Michael Fleischhauer
The ground-state phase diagram of mixtures of spin polarized fermions and bosons in a 1D periodic lattice is discussed in the limit of large fermion hopping and half filling of the…
The one-dimensional Bose-Fermi-Hubbard model in the heavy-fermion limit
A. Mering, M. Fleischhauer
We study the phase diagram of the zero-temperature, one-dimensional Bose-Fermi-Hubbard model for fixed fermion density in the limit of small fermionic hopping. This model can be re…
