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…

Perturbation theory for optical excitations in the one-dimensional extended Peierls--Hubbard model
Anja Grage, Florian Gebhard, Joerg Rissler
For the one-dimensional, extended Peierls--Hubbard model we calculate analytically the ground-state energy and the single-particle gap to second order in the Coulomb interaction fo…

Itineracy Effects on Spin Correlations in 1D Mott Insulators
M. J. Bhaseen, F. H. L. Essler, A. Grage
We consider spin correlations in the one dimensional half filled repulsive Hubbard model. For very large values of the on-site repulsion U the spin correlations are dominated by vi…
