dc.descriptionWithin the t-t'-J model, the physical properties of doped cuprates in the superconducting-state are discussed based on the kinetic energy driven superconducting mechanism. We show that the superconducting-state in cuprate superconductors is controlled by both superconducting gap parameter and single particle coherence, and then quantitatively reproduce some main features found in the experiments on cuprate superconductors, including the doping dependence of the superconducting gap parameter and superconducting transition temperature, the electron spectral function at [π,0] point, the charge asymmetry of superconductivity in the hole and electron doping, and the doping and energy dependence of the incommensurate magnetic scattering at both low and high energies and commensurate [π,π] resonance at intermediate energy. We also show that the incommensurate magnetic excitations at high energy have energies greater than the superconducting gap energy, and are present at the superconducting transition temperature.
