Abstract
Highly absorbing silica-based glasses exhibit a distinct minimum in the temperature dependence of the very-far-infrared absorption coefficient near 10 K. The associated anomalous absorption at lower temperature can be understood by the two-level tunneling model. Different amorphous materials manifest a considerable diversity in the anomalous behavior.Keywords
