Universal properties of low-temperature glass

Amorphous solids (glasses) present universal properties strikingly different from that of crystalline counterparts at low temperatures, regardless of their microscopic nature. Tunneling-two-level-system model (TTLS model) successfully explained several universalities below 1K, but it cannot explain the other glass low-temperature universal properties. Based on virtual phonon exchange interaction, we develop a glass generic coupled block model to discuss two universal properties: sound velocity/dielectric constant shift, and low-temperature mechanical avalanche problem. We also successfully explain the universal property of glass Meissner-Berret ratio by using our generic coupled block model.
