Spectral signatures of Holstein polarons
Holger Fehske, Andreas Alvermann, Martin Hohenadler +1
We review numerical results for ground-state and spectral properties of the single-electron Holstein model.
Quantum phase transitions in one-dimensional electron-phonon systems
Holger Fehske, Eric Jeckelmann
We discuss the Luttinger-liquid charge-density-wave and Peierls-insulator Mott-insulator quantum phase transitions in 1D electron-phonon systems.
Localisation versus self-trapping: Polaron formation in the Anderson-Holstein model
Holger Fehske, Franz X. Bronold, amd Andreas Alvermann
We discuss polaron formation in disordered electron-phonon systems.
Spectral functions of the spinless Holstein model
J. Loos, M. Hohenadler, H. Fehske
An analytical approach to the one-dimensional spinless Holstein model is proposed, which is valid at finite charge-carrier concentrations. Spectral functions of charge carriers are…
Phase diagram of the excitonic insulator
B. Hülsen, F. X. Bronold, H. Fehske +1
Motivated by recent experiments, which give strong evidence for an excitonic insulating phase in , we developed a scheme to quantitatively construct, for…
Hole doped Hubbard ladders
H. Fehske, G. Hager, G. Wellein +1
The formation of stripes in six-leg Hubbard ladders with cylindrical boundary conditions is investigated for two different hole dopings, where the amplitude of the hole density mod…
