Within the kinetic energy driven superconducting mechanism, the magnetic nature of cuprate superconductors is discussed. It is shown that the superconducting state is controlled by both charge carrier gap function and quasiparticle coherent weight. This quasiparticle coherent weight grows linearly w
We consider the effective extended Hubbard Hamiltonian for the cuprates, with nearest-neighbor hopping which depends on the occupation. Using exact diagonalization in a 4 โข 4 cluster, we obtain a large enhancement of d-wave pairing correlation functions for optimum doping. The physical picture is co
