摘要：
The magnetization curve of the infinite-dimensional Hubbard model is calculated by using the quantum Monte Carlo method. The calculated curve is essentially the same as that of the exact solution in one dimension and that of the Gutzwiller approximation, which suggests the same behavior in all the intermediate dimensions. Combined with the knowledge on the Anderson impurity, the change of the shape of the density of states of the Hubbard model under a magnetic field is discussed.
