This builds up an emission anisotropy and excitation transfer along the Bragg planes along with pronounced excitation localization.

We examine the somewhat unusual long-wavelength, low-frequency fluctuation spectra resulting from the existence of an infinite set of mutually coupled conserved densities of which the number density and energy density are two members. The analytically soluble infinite-mode correlation functions are compared with the corresponding functions obtained by truncating the set of slow modes at successively increasing orders. Furthermore, we evaluate the long-wavelength number density autocorrelation function for a fixed speed, v0, in terms of a frequency-dependent diffusivity D(oJ; v0) and obtain the fluctuation spectra of all conserved densities by an additional velocity average with the appropriate canonical weights. The effect of the frequency-dependent diffusivity D(~o; v0) on the density fluctuation spectra at frequencies small compared to the mean collision frequency is elucidated.
