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…

Luttinger liquid versus charge density wave behaviour in the one-dimensional spinless fermion Holstein model
H. Fehske, G. Wellein, G. Hager +3
We discuss the nature of the different ground states of the half-filled Holstein model of spinless fermions in 1D. In the metallic regime we determine the renormalised effective co…
