Phonon localization in glasses
Abstract
A universal but unexplained characteristic of glasses is the temperature-independent region or plateau in the thermal conductivity for temperatures 1--30 K. Examination of low-temperature thermal conductivity data for a wide variety of glasses indicates that the mean free path of the average thermal phonon becomes less than the phonon wavelength at temperatures in the vicinity of the plateau. Comparison with similar data in aggregates suggests that Ioffe-Regel localization of the vibrational modes occurs for phonons whose wavelength and mean free path are on the order of a structural correlation length of the material. Typical correlation lengths in glasses determined by this argument are 20--50 A\r{}. The universal plateau in bulk glasses is therefore associated with phonon localization due to strong scattering from inhomogeneities on this length scale.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
