Unusual quasi-one-dimensional electron dispersions in the spin-1/2 quantum magnet TiOCl
M. Hoinkis, M. Sing, J. Schaefer +8
We have studied the electronic structure of the spin-1/2 quantum magnet TiOCl by polarization-dependent momentum-resolved photoelectron spectroscopy. From that, we confirm the quas…

Optical conductivity of the one-dimensional dimerized Hubbard model at quarter filling
Holger Benthien, Eric Jeckelmann
We investigate the optical conductivity in the Mott insulating phase of the one-dimensional extended Hubbard model with alternating hopping terms (dimerization) at quarter band fil…

Density-matrix renormalisation group approach to quantum impurity problems
Satoshi Nishimoto, Eric Jeckelmann
A dynamic density-matrix renormalisation group approach to the spectral properties of quantum impurity problems is presented. The method is demonstrated on the spectral density of…
