| Abstract |
Monte Carlo simulations of the three-dimensional O(4) model in the ordered phase are performed to study the Goldstone mode effects. Our data show a distinct scaling region, where the Fourier-transformed transverse correlation function behaves as 1/k^lambda with lambda < 2 (lambda about 1.95), in disagreement with the standard theoretical prediction lambda = 2. |
