Strong Correlation Effects on the d-wave superconductor- Spectral Weight Analysis by Variational Wave Functions

We examine the strong correlation effects of the d-wave superconducting state by including the Gutzwiller projection for no electron double occupancy at the each lattice site. The spectral weights (SW's) for adding the removing an electron on the projected superconducting state, the ground state of the 2-dimensional t-t'-t"-J model with moderate doped holes describing the high T-c cuprates, are studies numerically on finite lattices and compared with the observation made by low-temperature tunneling (particle asymmetry of tunneling conductance) and angle-resolved photoemission (SW transfer from the projected Fermi liquid state) spectroscopies. The contrast with the d-wave case without projection is also presented.
