摘要：

The pair-pair correlation function of the two-dimensional t-J model is studied by using the power-Lanczos method under the assumption of monotonic behavior. In comparison with the results of the ideal Fermi gas, we conclude that the 2D t-J model does not have long-range d-wave superconducting correlation in the interesting parameter range of J/t less than or equal to 0.5. Implications of this result are also discussed.
