Scaling of the Non-Phononic Spectrum of Two-Dimensional Glasses

Lijin Wang, Grzegorz Szamel, Elijah Flenner

The scaling of the non-phononic spectrum for 2D systems has been recently debated. Here we provide evidence that the non-phononic spectrum $D_{ex}(\omega )\sim {\omega }^{\beta }$ where $\beta \approx 3.5$…
