摘要：

The boundary of phase separation of the two-dimensional t-J model is investigated by the power-lanczos method and Maxwell construction. The method is similar to a variational approach and it determines the lower bound of the phase-separation boundary with J(c)/t=0.6+/-0.1 in the limit n(e) similar to 1. In the physically interesting regime of high-T-c superconductors where 0.3<J/t<0.5 there is no phase separation.
