摘要：

We present a self-consistent strong-coupling scheme to evaluate the single-particle Green's function for the two-dimensional Hubbard model in the spin density wave state. We analyse the single-quasi-hole properties including its dispersion and spectral weight. Novel incoherent contributions to the spectral function resulting from multi-spin-wave processes are found and compared to similar results for the t-J model and small Hubbard clusters.
