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…

Quantum lattice dynamical effects on the single-particle excitations in 1D Mott and Peierls insulators
H. Fehske, G. Wellein, G. Hager +2
As a generic model describing quasi-one-dimensional Mott and Peierls insulators, we investigate the Holstein-Hubbard model for half-filled bands using numerical techniques. Combini…
