Abstract
The dynamics of Ginzburg-Landau (or "potential") systems driven away from equilibrium and subjected to noise is simulated numerically. It is found that the Fourier spectrum does not always have its peak at the wave number corresponding to the absolute minimum of the potential. This is explained heuristically on the basis of an entropy type of argument.Keywords
