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…
Many-polaron problem by cluster perturbation theory
Martin Hohenadler, Gerhard Wellein, Andreas Alvermann +1
The carrier-density dependence of the photoemission spectrum of the Holstein many-polaron model is studied using cluster perturbation theory combined with an improved cluster diago…
Photoemission spectra of many-polaron systems
M. Hohenadler, D. Neuber, W. von der Linden +3
The cross over from low to high carrier densities in a many-polaron system is studied in the framework of the one-dimensional spinless Holstein model, using unbiased numerical meth…
Temperature- and quantum phonon effects on Holstein-Hubbard bipolarons
Martin Hohenadler, Wolfgang von der Linden
The one-dimensional Holstein-Hubbard model with two electrons of opposite spin is studied using an extension of a recently developed quantum Monte Carlo method, and a very simple y…
Holstein polaron in two and three dimensions by quantum Monte Carlo
Martin Hohenadler, Hans Gerd Evertz, Wolfgang von der Linden
A recently developed quantum Monte Carlo approach to the Holstein model with one electron [PRB 69, 024301 (2004)] is extended to two and three dimensional lattices. A moderate sign…
Quantum Monte Carlo and variational approaches to the Holstein model
Martin Hohenadler, Hans Gerd Evertz, Wolfgang von der Linden
Based on the canonical Lang-Firsov transformation of the Hamiltonian we develop a very efficient quantum Monte Carlo algorithm for the Holstein model with one electron. Separation…
