Light impurities in covalent materials, such as H or O in Si, are characterized by high-frequency local vibrational modes (LVMs) far above the phonon frequencies of the host crystal. Upon excitation, such LVMs are expected to have long lifetimes since their decay involve multi-phonon processes. Yet,
