Thermodynamics of Adiabatically Loaded Cold Bosons in the Mott Insulating Phase of One-Dimensional Optical Lattices
K. P. Schmidt, A. Reischl, G. S. Uhrig
In this work we give a consistent picture of the thermodynamic properties of bosons in the Mott insulating phase when loaded adiabatically into one-dimensional optical lattices. We…
Temperature in One-Dimensional Bosonic Mott insulators
A. Reischl, K. P. Schmidt, G. S. Uhrig
The Mott insulating phase of a one-dimensional bosonic gas trapped in optical lattices is described by a Bose-Hubbard model. A continuous unitary transformation is used to map this…
Systematic Mapping of the Hubbard Model to the Generalized t-J Model
Alexander Reischl, Erwin Müller-Hartmann, Götz S. Uhrig
The generalized t-J model conserving the number of double occupancies is constructed from the Hubbard model at and in the vicinity of half-filling at strong coupling. The construct…
Derivation of effective spin models from a three band model for CuO_2-planes
E. Müller-Hartmann, A. Reischl
The derivation of effective spin models describing the low energy magnetic properties of undoped CuO_2-planes is reinvestigated. Our study aims at a quantitative determination of t…
