Itinerant and high-energy localized single-particle spectra in large-U high-Tc cuprates
O. S. Barišić, S. Barišić
A theory of the underlying metallic state of large-U high-Tc cuprates is presented starting from the covalent Cu-2O 3-band model associated with a sufficiently small copper occ…
Multiband responses in high-Tc cuprate superconductors
G. Nikšić, I. Kupčić, O. S. Barišić +2
We report on the interplay of localized and extended degrees of freedom in the metallic state of high-temperature superconductors in a multiband setting. Various ways in which the…
The effect of large on the Raman spectrum in the copper-oxide superconductors
H. Niksic, E. Tutis, S. Barisic
The effect of the charge fluctuations on the electronic and Raman spectrum of high temperature superconductors is examined, using the slave boson approach to the large Coulomb repu…
THE TIGHT-BINDING APPROACH TO THE DIELECTRIC RESPONSE IN THE MULTIBAND SYSTEMS
P. Zupanovic, A. Bjelis, S. Barisic
Starting from the random phase approximation for the weakly coupled multiband tightly-bounded electron systems, we calculate the dielectric matrix in terms of intraband and interba…
