Phase Separation of the Two-Dimensional t-J model
C. T. Shih, Y. C. Chen, T. K. Lee
Abstract
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 Jc/t=0.6 0.1 in the limit ne 1. In the physical interesting regime of high Tc superconductors where 0.3<J/t<0.5 there is no phase separation.
