Kondo impurity between superconducting and metallic reservoir: the flow equation approach
M. Zapalska, T. Domanski
It is well established that a correlated quantum impurity embedded in a metallic host can form the many-body Kondo state with itinerant electrons due to the effective antiferromagn…
Flow equation approach to the linear response theory of superconductors
M. Zapalska, T. Domanski
We apply the flow equation method for studying the current-current response function of electron systems with the pairing instability. To illustrate the specific scheme in which th…
Spectroscopic Bogoliubov features near the unitary limit
T. Domanski
We analyze the single particle excitation spectrum of the ultracold fermion atom system close to the unitary limit where there has been found experimental evidence for the Bogoliub…
Boson-Fermion Duality and Metastability in Cuprate Superconductors
J. Ranninger, T. Domanski
The intrinsic structural metastability in cuprate high T materials, evidenced in a checker-board domain structure of the CuO planes, locally breaks translational and rotati…
Quantum fluctuations of the ultracold atom-molecule mixtures
T. Domanski
We investigate evolution of the quantum coherence in the ultracold mixture of fermionic atoms and bosonic dimer molecules. Interactions are there experimentally controlled via tuni…
Interplay between the single particle and collective features in the boson fermion model
T. Domanski, J. Ranninger
We study the interplay between the single particle and fermion pair features in the boson fermion model, both above and below the transition temperature , using the flow equ…
Renormalization group approach to the interacting boson fermion systems
T. Domanski, J. Ranninger
We study a pseudogap region of the mixed boson fermion system using a recent formulation of the renormalization group technique through the set of infinitesimal unitary transformat…
Non-linear feedback effects in coupled Boson-Fermion systems
T. Domanski, J. Ranninger
We address ourselves to a class of systems composed of two coupled subsystems without any intra-subsystem interaction: itinerant Fermions and localized Bosons on a lattice. Switchi…
The Atomic Limit of the Boson-Fermion Model
T. Domanski, J. Ranninger, J. M. Robin
The Boson-Fermion model, describing a mixture of hybridized localized Bosons and itinerant Fermions on a lattice, is known to exhibit spectral properties for the Fermions which upo…
