摘要：

The moderately doped (greater-than-or-equal-to 10% holes) t-J model is shown to have a large electronic Fermi surface, compatible with Luttinger's theorem. The full single-particle Green's function is calculated by diagonalization techniques. We present strong evidence for quasiparticle-like behavior, with a dispersion consistent with the bandstructure of the noninteracting limit, and a width of the coherent band scaling proportional to J for J < t.
