Bose-Einstein condensation driven superconductivity in HT c SC

  • Jalius Ranninger
HTSC—Theory

Abstract

We explore a scenario in which localized bi-polarons exchange with itinerant electrons and thus lead to a superfluid state of the bosonic bi-polarons which essentially control the superconductivity in such systems. Normal state properties of such a scenario discussed here in detail should be the testing ground of the validity of such a picture for highT c superconductors (HT c SC).
