چکیده

We investigate the superconductivity of a three-dimensional d-p model with a multilayer perovskite structure on the basis of the second-order perturabation theory within the weak coupling framework. Our model has been designed with multilayer high-Tc superconducting cuprates in mind. In our model, multiple Fermi surfaces appear, and the component of a superconducting gap function develops on each band. We have found that the multilayer structure can stabilize the superconductivity in a wide doping range.

Crossover from Weak- to Strong-Coupling Superconductivity and to Normal State with Pseudogap

For an electron gas with a δ-function attraction we investigate the crossover from weak-coupling to strong-coupling superconductivity near zero temperature as well as near the temperature T , at which the strong coupling produces a pseudogap in the energy spectrum due to the binding of electron pairs. We present curves for the behavior of the superconductive transition temperature, the gap form...

PEROVSKITE-TYPE OXIDES - THE NEW APPROACH TO HIGH-Tc SUPERCONDUCTIVITY

In our Lecture, we take the opportunity to describe the guiding ideas and our effort in the search for high-T, superconductivity. They directed the way from the cubic niobium-containing alloys to layered copper-containing oxides of perovskite-type structure. We shall also throw some light onto the circumstances and the environment which made this breakthrough possible. In the second part, prope...

Fröhlich-Coulomb model of high-temperature superconductivity and charge segregation in the cuprates. Abstract. We introduce a generic Fröhlich-Coulomb model of the oxides, which also includes infinite on-site (Hubbard) repulsion, and describe a simple analytical method of solving the multi-polaron problem in complex lattice structures. Two particular lattices, a zigzag ladder and a perovskite l...

superconductivity ∗

We present a 2+1-dimensional lattice model for the copper oxide superconductors and their parent compounds, in which both the charge and spin degrees of freedom are treated dynamically. The spin-charge coupling parameter is associated to the doping fraction in the cuprates. The model is able to account for the various phases of the cuprates and their properties, not only at low and intermediate...
