Suppression of tunneling two-level systems in ultrastable glasses of indomethacin
Suppression of tunneling two-level systems in ultrastable glasses of indomethacin
Glasses and other non-crystalline solids exhibit thermal and acoustic properties at low temperatures anomalously different from those found in crystalline solids, and with a remarkable degree of universality. Below a few K, these universal properties have been successfully interpreted using the Tunneling Model, which has enjoyed (almost) unanimous recognition for …
