Bogoliubov shadow bands in the normal state of superconducting systems with strong pair fluctuations
T. Domanski, J. Ranninger
On the basis of a scenario where electron pairing is induced by resonant two-particle scattering (the Boson Fermion model), we show how precursors of the superconducting state - in…

Nature of correlations in the atomic limit of the boson fermion model
T. Domanski
Using the equation of motion technique for Green's functions we derive the exact solution of the boson fermion model in the atomic limit. Both (fermion and boson) subsystems are ch…

Feshbach resonance described by the boson fermion coupling
T. Domanski
We consider a possibility to describe the Feshbach resonance in terms of the Boson Fermion (BF) model. Using such model we show that after a gradual disentangling of the boson from…
