Series studies of the spin-1/2 Heisenberg antiferromagnet at T=0: Magnon dispersion and structure factors

摘要

We have extended our previous series studies of quantum antiferromagnets at zero temperature by computing the one-magnon dispersion curves and various structure factors for the linear chain, square, and simple cubic lattices. Many of these results are a substantial extension of previous work. These results are directly comparable to neutron-scattering experiments, and we make such comparisons where possible.
