Excitation spectra and spin gap of the half-filled Holstein-Hubbard model
Martin Hohenadler, Fakher F. Assaad
Single-- and two-particle excitation spectra of the one-dimensional, half-filled Holstein-Hubbard model are calculated using the continuous-time quantum Monte Carlo method. In the…
Correlation effects in two-dimensional topological insulators
M. Hohenadler, F. F. Assaad
Topological insulators have become one of the most active research areas in condensed matter physics. This article reviews progress on the topic of electronic correlations effects…
Peierls to superfluid crossover in the one-dimensional, quarter-filled Holstein model
Martin Hohenadler, Fakher F. Assaad
We use continuous-time quantum Monte Carlo simulations to study retardation effects in the metallic, quarter-filled Holstein model in one dimension. Based on results which include…
Effect of Electron-Phonon Interaction Range for a Half-Filled Band in One Dimension
Martin Hohenadler, Fakher F. Assaad, Holger Fehske
We demonstrate that fermion-boson models with nonlocal interactions can be simulated at finite band filling with the continuous-time quantum Monte Carlo method. We apply this metho…
Interaction-range effects for fermions in one dimension
Martin Hohenadler, Stefan Wessel, Maria Daghofer +1
Experiments on quasi-one-dimensional systems such as quantum wires and metallic chains on surfaces suggest the existence of electron-electron interactions of substantial range and…
