Abstract

The connected Hamiltonian moments (Hn)c of the one-dimensional s = ~ Heisenberg model with respect to the Neel state are calculated up to n = 17. Subsequent calculation of the Hamiltonian moments (Hn) allows the first nine iterations of the Lanczos diagonalisation to be determined analytically for arbitrary lattice size.
