Hardcore Magnons in the S=1/2 Heisenberg Model on the Square Lattice
Kai P. Schmidt, Götz S. Uhrig
We propose a versatile approach to treat commonly arising constraints. It is illustrated for interacting magnons of the Heisenberg antiferromagnet on a square lattice. For systems…
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…
Electron spectra close to a metal-to-insulator transition
Michal Karski, Carsten Raas, Götz S. Uhrig
A high-resolution investigation of the electron spectra close to the metal-to-insulator transition in dynamic mean-field theory is presented. An all-numerical, consistent confirmat…
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…
Zero-field incommensurate spin-Peierls phase with interchain frustration in TiOCl
R. Rückamp, J. Baier, M. Kriener +7
We report on the magnetic, thermodynamic and optical properties of the quasi-one-dimensional quantum antiferromagnets TiOCl and TiOBr, which have been discussed as spin-Peierls com…
Magnetic Excitations in Bilayer High-Temperature Superconductors with Stripe Correlations
G. S. Uhrig, K. P. Schmidt, M. Grüninger
The universal behaviour of the magnetic excitations in high-temperature superconductors is described in a model with static stripes retaining only the localized spin degrees of fre…
