Hello, I'm fascinated by the cuprate superconductors. But what is the mechanism for high temperature superconductivity? Perhaps the Jahn-Teller-Effect in copper oxide. The electrons for example in magnetite become localized at low temperatures which leads to non-conductivity. I guess the strong electron-phonon coupling in copper oxides suppresses the freezing of electrons around the atoms. The motions of the atoms keep the electrons on moving via the electron-phonon coupling. At temperatures near the absolute zero point when the atoms stop moving the superconductivity in copper oxide superconductors vanishes? One should test it!
