Spin and charge dynamics of the one-dimensional extended Hubbard model
H. Benthien, E. Jeckelmann
We investigate the dynamical spin and charge structure factors and the one-particle spectral function of the one-dimensional extended Hubbard model at half band-filling using the d…
Quantum phase transition in the one-dimensional extended Peierls-Hubbard model
H. Benthien, F. H. L. Essler, A. Grage
We consider the one-dimensional extended Hubbard model in the presence of an explicit dimerization . For a sufficiently strong nearest neighbour repulsion we establish the exist…
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…
Spectral function of the one-dimensional Hubbard model away from half filling
H. Benthien, F. Gebhard, E. Jeckelmann
We calculate the photoemission spectral function of the one-dimensional Hubbard model away from half filling using the dynamical density matrix renormalization group method. An app…
Resonant inelastic x-ray scattering study of holon-antiholon continuum in SrCuO2
Young-June Kim, J. P. Hill, H. Benthien +9
We report a resonant inelastic x-ray scattering study of charge excitations in the quasi-one-dimensional Mott insulator SrCuO2. We observe a continuum of low-energy excitations, in…
