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…

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…

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…
