Analytical approach to the quantum-phase transition in the one-dimensional spinless Holstein model
S. Sykora, A. Huebsch, K. W. Becker
We study the one-dimensional Holstein model of spinless fermions interacting with dispersion-less phonons by using a recently developed projector-based renormalization method (PRM)…

Valence transition in the periodic Anderson model
A. Huebsch, K. W. Becker
A very rich phase diagram has recently been found in CeCuSi from high pressure experiments where, in particular, a transition between an intermediate valence configurat…

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…
