摘要：

We study the behavior of the mean number of particles <n> (density) as a function of the chemical potential mu in the two-dimensional Hubbard model, using a quantum Monte Carlo method. Working at U/t = 10, 4, and -4 on lattices with 4 X 4, 6 X 6, and 8 X 8 sites, we do not find evidence of phase separation.
