Query: Universal amplitude ratios in finite-size scaling: three-dimensional
  Ising model   Motivated by the results of two-dimensional conformal field theory (CFT) we
investigate the finite-size scaling of the mass spectrum of an Ising model on
three-dimensional lattices with a spherical cross section. Using a
cluster-update Monte Carlo technique we find a linear relation between the
masses and the corresponding scaling dimensions, in complete analogy to the
situation in two dimensions. Amplitude ratios as well as the amplitudes
themselves appear to be universal in this case.
