摘要：

The renormalization of the extended Hubbard model proposed by Zhang and Rice [Phys. Rev. B 37, 3759 (1988)] that leads to the (nearest-neighbor-only) t-J model is scrutinized in the infinite correlation limit. We demonstrate that the Ud,Up limit obtained from the extended Hubbard model does not have the same ground state as the U extrapolation of the t-J model. © 1990 The American Physical Society.
