Mechanisms of high temperature superconductivity

摘要: The focal points of the symposium presented in this book were following: For high temperature copper oxide superconductors, general consensus was that electron correlation effects are essential importance. Based on understanding a number discussions took place: how to include and relative importance various interactions; whether ground state normal is Fermi-liquid-like or not; where doped holes mainly exist nature these holes; value ratio energy gap critical temperature; mechanics s magnetic, charge fluctuation, excitonic, very unusual ones quite different from Fermi-liquid picture; phase abnormal, etc. Bi-O such as BaKBiO system, discussion concentrated not mechanism superconductivity same superconductors.
