d-Wave Pairing Correlation in the Two-Dimensional t-J Model

Abstract

The pair-pair correlation function of the two-dimensional t-J model is studied by using the power-Lanczos method and an 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 $J/t\le 0.5$. Implications of this result will also be discussed.
