Stripe formation in doped Hubbard ladders
G. Hager, G. Wellein, E. Jeckelmann +1
We investigate the formation of stripes in $7\chunks \times 6$ Hubbard ladders with $4\chunks$ holes doped away from half filling using the density-matrix renormalization group (DM…

Optical excitations of Peierls-Mott insulators with bond disorder
J. Rissler, E. Jeckelmann, F. Gebhard
The density-matrix renormalization group (DMRG) is employed to calculate optical properties of the half-filled Hubbard model with nearest-neighbor interactions. In order to model t…

Comment on "Accurate ground-state phase diagram of the one-dimensional extended Hubbard model at half filling"
Eric Jeckelmann
In PRB 68, 153101 (2003), Guoping Zhang presented density-matrix renormalization group (DMRG) results which contradict my DMRG calculations and Hirsch's quantum Monte Carlo (QMC) s…
