By combining a generalized Lanczos scheme with the variational Monte Carlo method, we can optimize the short- and long-range properties of the ground state separately. This allows us to measure the long-range order of the ground state of the t-J model as a function of the coupling constant J/t , and identify a region of finite d -wave superconducting long-range order. With a lattice size of 50 sites we can reliably examine hole densities down to 0.16.
