Abstract : Thermal properties of glasses are successfully described with a model consisting of two-level systems (spins) coupled to a phonon bath. In most treatments, it is assumed that the spin-phonon interaction is weak. However, recent detailed examinations have revealed that this assumption is not justified and that, therefore, the spin-phonon interaction is important for understanding physical properties of glassy materials. In this paper, we examine the implications of strong spin-phonon interaction on the spectral diffusion.
