Query: Models for the description of uniaxially modulated materials   Models which allow an explicit application to structurally modulated
substances are reviewed within the frame of a symmetry-based approach starting
from discrete lattice theory. Focus is set on models formulated in terms of
local variables assigned to discrete crystallographic units (unit cells or
parts of them). Especially considered are symmetry-based pseudo spin models.
Methods are discussed which permit the handling of the statistical mechanics of
such models, the translation of model calculation results to a form allowing
the prediction of experimental data, and the theoretical determination of point
defect influences.
