Abstract
We show that the relaxational dynamics as exhibited in the enthalpy relaxation of the density wave compounds at very low temperatures (T<1K) is very similar to that one occuring in disordered systems such as glassy polymers or spin glasses. We discuss these similarities, as well as some pecularities, in the frame of secondary relaxational processes as genuine features of glass formers below their glass transition temperature. This approach is strongly supported by recent direct evidence for the existing glass transition brought about by means of calorimetric and dielectric measurements.
