Phase separation in the two-dimensional t-J model

By Shih CT


[[abstract]]The power-Lanczos method, a Green's function Monte-Carlo simulation. is used to calculate the energies of the two-dimensional t-J model up to 122 sites. The phase boundary of phase separation of the model is then determined by the Maxwell construction. Our conclusion is that there is no phase separation for J less than or equal to 0.4.
