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…
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…
Mixed-phase description of colossal magnetoresistive manganites
Alexander Weiße, Jan Loos, Holger Fehske
In view of recent experiments, indicating the spatial coexistence of conducting and insulating regions in the ferromagnetic metallic phase of doped manganites, we propose a refined…
Competition of Zener and polaron phases in doped CMR manganites
A. Weisse, J. Loos, H. Fehske
Inspired by the strong experimental evidence for the coexistence of localized and itinerant charge carriers close to the metal-insulator transition in the ferromagnetic phase of co…
Considerations on the quantum double-exchange Hamiltonian
A. Weisse, J. Loos, H. Fehske
Schwinger bosons allow for an advantageous representation of quantum double-exchange. We review this subject, comment on previous results, and address the transition to the semicla…
