Abstract
Inelastic neutron scattering and thermal conductivity data suggest tha t vibrational modes in quasicrystals are mostly confined into the basi c atomic clusters of their self-similar structure. Heat transport obey s a hierarchically variable range hopping mechanism and shows power la w dependence on temperature each side of a plateau of constant conduct ivity around 50 K.
