摘要：

We show how the Green's-function Monte Carlo method can be used to compute accurately the ground-state energy of the two-dimensional t-J model for lattices of large size. This is demonstrated for the case of a single hole, with the aid of suitable initial and guidance functions. Our transient estimates for the ground-state energy of the 4 x 4 lattice are in remarkable agreement with the exact values; we report results for lattices of significantly larger size than 4 x 4.
