Resonating Valence Bond

In this talk the Resonating Valence Bond (RVB) state of the Mott- Hubbard insulator and the high temperature superconductivity resulting from doping are described as the possible mechanisms for the insulating and high temperature superconducting properties of undoped and doped La2CuO4 and other high Tc oxides. We describe in detail two microscopic approaches to the understanding of the RVB superconductivity- one is a simple mean field theory and the other is a gauge theory.
