摘要：

Monte Carlo results for the frequency dependent conductivity sigma1(omega), the angular resolved photoemission spectral weight A(p,omega), and the electron momentum distribution [n(p)] are calculated for a half-filled Hubbard model with the on-site Coulomb interaction U equal to the bandwidth 8t. We find that even for U = 8t, a spin-density-wave approximation provides a sensible description of this data and hence a useful picture of the electronic degrees of freedom in the insulating state.
