Fluctuation conductivity due to the preformed local pairs
T. Domanski, M. Baranska, A. L. Solovjov
We investigate the properties of a system where the itinerant electrons coexist and interact with the preformed local pairs. Using the nonperturbative continuous unitary transforma…
Quasiparticle states driven by a scattering on the preformed electron pairs
T. Domanski
We analyze evolution of the single particle excitation spectrum of the underdoped cuprate superconductors near the anti-nodal region, considering temperatures below and and above t…
Constructive influence of the induced electron pairing on the Kondo state
T. Domanski, I. Weymann, M. Baranska +1
Superconductivity and magnetism are usually the conflicting (competing) phenomena. We show, however, that in nanoscopic objects the electron pairing may promote the magnetic orderi…
Enhancements of Andreev conductance induced by the photon/vibron scattering
J. Baranski, T. Domanski
We analyze the subgap spectrum and transport properties of the quantum dot embedded between one superconducting and another metallic reservoirs and additionally coupled to an exter…
Localization-delocalization dichotomy: Inherent spectral properties of the cuprates
J. Ranninger, T. Domanski
We consider hole pairing in the pseudopgap phase of High T_c cuprates, as arising from resonant scattering on dynamically deformable molecular units. As a result, localized and del…
Meservey-Tedrow-Fulde effect in a quantum dot embedded between metallic and superconducting electrodes
T. Domanski, A. Donabidowicz, K. I. Wysokinski
Magnetic field applied to the quantum dot coupled between one metallic and one superconducting electrode can produce a similar effect as has been experimentally observed by Meserve…
Comment on `Evidence for pairing above Tc from the dispersion in the pseudogap phase of cuprates' by A. Kanigel et al
T. Domanski, J. Ranninger
In a recent preprint [0803.3052] A. Kanigel et al report evidence for Bogoliubov-type excitations in the pseudogap phase in the anti-nodal region, where a robust pseudogap remains…
Unconventional particle-hole mixing in the systems with strong superconducting fluctuations
T. Domanski
Development of the STM and ARPES spectroscopies enabled to reach the resolution level sufficient for detecting the particle-hole entanglement in superconducting materials. On a qua…
The flow equation approach to the pairing instability problem
T. Domanski, A. Donabidowicz
By means of the continuous unitary transformation similar to a general scheme of the Renormalization Group (RG) procedure we study the issue of symmetry breaking and pairing instab…
Flow equation approach to the pairing problems
T. Domanski
We apply the flow equation method for studying the fermion systems where pairing interactions can either trigger the BCS instability with the symmetry breaking manifested by the of…
Remnant superfluid collective phase oscillations in the normal state of systems with resonant pairing
T. Domanski, J. Ranninger
The signature of superfluidity in bosonic systems is a sound wave-like spectrum of the single particle excitations which in the case of strong interactions is roughly temperature i…
Ultracold atom superfluidity induced by the Feshbach resonance
T. Domanski
We discuss the possible signatures of superfluidity induced by the Feshbach resonance in ultracold gas of fermion atoms. Approaching the phase transition from above there appear va…
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…
Thermodynamics and tunneling spectroscopy in the pseudogap regime of the boson fermion model
T. Domanski, J. Ranninger
Motivated by the STM experimental data on Bi_2 Sr_2 CaCU_2 O_{8+x} which indicate the tunneling conductance asymmetry sigma(-V) not equal sigma(V), we report that such a behavior c…
Upward curvature of the upper critical field in the Boson--Fermion model
Tadeusz Domanski, Maciej M. Maska, Marcin Mierzejewski
We report on a non-conventional temperature behavior of the upper critical field () which is found for the Boson-Fermion (BF) model. We show that the BF model properly r…
