Description

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 analyze the single quasi-hole properties including its dispersion and the spectral weight. Novel incoherent contributions to the spectral function resulting from multi-spin wave processes are discussed. ((orig.))
