Query: Quantum structure of glasses and the boson peak: a theory of vibrations   We present a novel analytical model for glasses, starting from the first
principle that the disorder in a glass mimics the disorder in a fluid. The
origin of the boson peak is attributed to the intrinsically noncommutative
geometry of the fluid disorder, which induces a van Hove singularity in the
vibrational density of states. The universality of the model is exhibited by
applying it to amorphous silicon, vitreous GeO$_2$ and
Ba$_{8}$Ga$_{16}$Sn$_{30}$ clathrate, which show a remarkable agreement between
the theoretical predictions for specific heat and the experimental data.
