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…
Crystallization in two-component Coulomb systems
M. Bonitz, V. S. Filinov, V. E. Fortov +2
The analysis of Coulomb crystallization is extended from one-component to two-component plasmas. Critical parameters for the existence of Coulomb crystals are derived for both clas…
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…
Optical absorption and activated transport in polaronic systems
G. Schubert, G. Wellein, A. Weiße +2
We present exact results for the optical response in the one-dimensional Holstein model. In particular, by means of a refined kernel polynomial method, we calculate the ac and dc e…
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…
Local distribution approach to disordered binary alloys
Andreas Alvermann, Holger Fehske
We study the electronic structure of the binary alloy and (quantum) percolation model. Our study is based on a self-consistent scheme for the distribution of local Green functions.…
