Query: Numerical evidence for Goldstone-mode effects in the three-dimensional
  O(4)-model   We investigate the three-dimensional O(4)-model on 24^3--96^3 lattices as a
function of the magnetic field H. Below the critical point, in the broken
phase, we confirm explicitly the H^{1/2} dependence of the magnetization and
the corresponding H^{-1/2} divergence of the longitudinal susceptibility, which
are predicted from the existence of Goldstone modes. At the critical point the
magnetization follows the expected finite-size-scaling behavior, with critical
exponent delta = 4.87(1).
