abstract = {There is ample evidence both from computer simulation and
experiments that the structural disorder characterizing
glasses and amorphous materials leads to quasi-localized
vibrations (QLVs). The effect of these modes on low
temperature properties such as heat capacity and conduction
or tunnelling can be calculated in the framework of the soft
potential model. Recently it has been shown that this
concept can be extended to describe the boson peak (BP). By
interaction, the density of states of the QLVs is changed to
a characteristic shape corresponding to the boson peak in
inelastic scattering. The QLVs interact with the sound waves
and dampen them. We show that resonant scattering between
QLVs and sound waves can describe the strong damping
observed experimentally. (C) 2010 Elsevier B.V. All rights
