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…
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…
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…
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…
