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…

Boson-controlled quantum transport
A. Alvermann, D. M. Edwards, H. Fehske
We study the interplay of collective dynamics and damping in the presence of correlations and bosonic fluctuations within the framework of a newly proposed model, which captures th…

Polaronic Quasiparticles in a Strongly Correlated Electron Band
W. Koller, A. C. Hewson, D. M. Edwards
We show that a strongly renormalized band of polaronic quasiparticle excitations is induced at the Fermi level of an interacting many-electron system on increasing the coupling of…
