  Article: How to calculate correlation functions of Heisenberg chains

  ABSTRACT: We describe a method for calculating dynamical spin-spin correlation functions in the finite isotropic and anisotropic antiferromagnetic Heisenberg models. Our method is able to produce results with high accuracy over the full parameter space.

  Article: Computation of dynamical correlation functions of heisenberg chains in a magnetic field.

  Jean-Sébastien Caux, Jean Michel Maillet
  [show abstract] [hide abstract]
  ABSTRACT: We compute the momentum- and frequency-dependent longitudinal spin structure factor for the spin-1/2 XXZ Heisenberg spin chain in a magnetic field, using exact determinant representations for form factors on the lattice. Multiparticle (i.e., multispinon) contributions are computed numerically throughout the Brillouin zone, yielding saturation of the sum rule to high precision.
