Abstract EN
We use an extended version of the standard tunneling model to explain the anisotropic sound absorption in decagonal quasicrystals.
The glassy properties are determined by an ensemble of two level systems (TLSs), arbitrarily oriented.
The TLS is characterized by a 3 × 3 symmetric tensor, [T], which couples to the strain field, [S], through a 3 × 3 × 3 × 3 tensor of coupling constants, [R].
The structure of [R] reflects the symmetry of the quasicrystal.
We also analyze the probability distributions of the elements of [T] in this particular model for a better understanding of the characteristics of “isotropic” and “anisotropic” distributions of the ensemble of TLSs.
We observe that the distribution of the elements is neither simple nor intuitive and therefore it is difficult to guess it a priory, using qualitative arguments based on the symmetry properties.
