One-Dimensional Quantum Transport Affected by a Background Medium: Fluctuations versus Correlations
S. Ejima, H. Fehske
We analyze the spectral properties of a very general two-channel fermion-boson transport model in the insulating and metallic regimes, and the signatures of the metal-insulator qua…

DMRG analysis of the SDW-CDW crossover region in the 1D half-filled Hubbard-Holstein model
S. Ejima, H. Fehske
In order to clarify the physics of the crossover from a spin-density-wave (SDW) Mott insulator to a charge-density-wave (CDW) Peierls insulator in one-dimensional (1D) systems, we…

Luttinger parameters and momentum distribution function for the half-filled spinless fermion Holstein model: A DMRG approach
S. Ejima, H. Fehske
We reexamine the nature of the metallic phase of the one-dimensional half-filled Holstein model of spinless fermions. To this end we determine the Tomonaga-Luttinger-liquid correla…
