High Tc superconductivity electronics.

Understanding High Tc Superconductivity ∗.

I briefly review several key issues in understanding the cuprate superconductors from the point of view of doped-Mott-insulator. Then I present an effective low-energy theory and show that the phase diagram of such a model includes an anti-ferromagnetic (AF) phase, a superconducting state, and a pseudogap phase at low doping and low temperature, consistent with the experimental one. The dual to...

High Tc superconductivity by quantum confinement

We report the results of a careful expenmental investigation of trie Cu site configurations in the Cu02 Plane of B12Sr2CaCu208+y (B12212) showing tbat trie quasi 2D Fermi liquid is confined in trie stripes of width L with a superlattice period

Generalized Statistics and High Tc Superconductivity

Introducing the generalized, non-extensive statistics proposed by Tsallis [1], into the standard s-wave pairing BCS theory of superconductivity in 2D yields a reasonable description of many of the main properties of high temperature superconductors, provided some allowance is made for non-phonon mediated interactions. The discovery of superconductivity in the copper oxides in 1986 [2] and the s...
