DESCRIPTION:I will review recent experiments on the cuprate superconductors in the context of a proposed phase diagram as a function of applied magnetic field\, temperature\, and hole/electron-doping. The theory of spin-fluctuation mediated pairing at large doping must be modified to apply in the underdoped regime. The modified theory includes the pocket structure of the Fermi surface and effects associated with the proximity of the Mott insulator. The theory predicts the competition between spin density wave order and superconductivity\, and I discuss how its quantum criticality is connected with the global cuprate phase diagram.
