In silico broadband mechanical spectroscopy of amorphous tantala
Adopting an agnostic approach, the quality factor Q of tantala glass is drawn via in silico mechanical spectroscopy in wide ranges of temperature (10–300 K) and frequency (500MHz≤f≤1THz). At the highest frequencies, Q∝f^{−3}, consistent with Rayleigh sound scattering. For frequencies lower than tera...
