title: Spatial and temporal spectra of noise driven stripe patterns.
abstract: Spatial and temporal noise power spectra of stripe patterns are investigated, using as a model a Swift-Hohenberg equation with a stochastic term. In particular, the analytical and numerical investigations show: (1) the temporal noise spectra are of 1/f(alpha) form, where alpha=1+(3-D)/4 with D the spatial dimension of the system; (2) that the stochastic fluctuations of the stripe position are subdiffusive.
