On the ratio between longitudinal and transverse Ioffe-Regel frequencies in glasses
Licun Fu, Mingyu Zhu, Xinyu Chang +1
The temperature dependence of thermal conductivity in glasses differs characteristically from that in crystals, and is largely controlled by how sound waves are damped. The Ioffe-R…

Correlation between the boson peak frequency and transverse Ioffe-Regel limit in four-dimensional structural glasses
Licun Fu, Xinyu Chang, Lijin Wang
The emergence of excess vibrational modes over the Debye prediction, typically manifested as the well-known boson peak in the plot of vibrational density of states scaled by the De…
