Abstract

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 quasihole properties including its dispersion and its spectral weight factor. Significant incoherent contributions to the spectral function are found resulting from multi spin wave processes in accordance with similar results for the t-J model and small Hubbard clusters.
