Correlation-induced metal insulator transition in a two-channel fermion-boson model
G. Wellein, H. Fehske, A. Alvermann +1
We investigate charge transport within some background medium by means of an effective lattice model with a novel form of fermion-boson coupling. The bosons describe fluctuations o…
Stochastic Green's function approach to disordered systems
A. Alvermann, H. Fehske
Based on distributions of local Green's functions we present a stochastic approach to disordered systems. Specifically we address Anderson localisation and cluster effects in binar…
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.
Electron transport in the Anderson model
A. Alvermann, F. X. Bronold, H. Fehske
Based on a selfconsistent theory of localization we study the electron transport properties of a disordered system in the framework of the Anderson model on a Bethe lattice. In the…
