We apply the model introduced in Phys. Rev. B 75, 064202 (2007), cond-mat/0610469, to calculate the anisotropy effect in the interaction of two level systems with phonons in disordered crystals. We particularize our calculations to cubic crystals and compare them with the available experimental data to extract the parameters of the model. With these parameters we calculate the interaction of the dynamical defects in the disordered crystal with phonons (or sound waves) propagating along other… 
Scattering of phonons on two-level systems in disordered crystals
We calculate the scattering rates of phonons on two-level systems in disordered trigonal and hexagonal crystals. We apply a model in which the two-level system, characterized by a direction in space,
Dissipation induced by phonon elastic scattering in crystals
TLDR
It is demonstrated that the phonon elastic scattering leads to a dominant dissipation in crystals at low temperature, and some clues to improve the performance of mechanical resonators, apply the desired defects, or reveal the atom configuration in lattice structure of disordered crystals.
The anisotropic glass-like properties of disordered crystals
The low temperature acoustic and thermal properties of amorphous, glassy materials are remarkably similar. All these properties are described theoretically with reasonable quantitative accuracy by
The Anisotropic Glassy Properties of Decagonal Quasicrystals
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
Decoherence spectroscopy with individual two-level tunneling defects
TLDR
A superconducting qubit is utilized to explore the quantum state evolution of coherently operated TLSs in order to shed new light on their individual properties and environmental interactions and identifies a frequency-dependence of TLS energy relaxation rates that can be explained by a coupling to phononic modes rather than by anticipated mutual TLS interactions.
