Glasses possess more low-frequency vibrational modes than predicted by Debye theory. These excess modes are crucial for the understanding of the low temperature thermal and mechanical properties of glasses, which differ from those of crystalline solids. Recent simulational studies suggest that the density of the excess modes scales with their frequency ω as ω in two and higher dimensions. Here, we present extensive numerical studies of two-dimensional model glass formers over a large range of… Expand

Low-energy quasilocalized excitations in structural glasses
Glassy solids exhibit a wide variety of generic thermomechanical properties, ranging from universal anomalous specific heat at cryogenic temperatures to nonlinear plastic yielding and failure underExpand
Sound attenuation in low temperature amorphous solids is primarily determined by non-affine displacements
Sound attenuation in low temperature amorphous solids originates from their disordered structure. However, its detailed mechanism is still being debated. Here we analyze sound attenuation startingExpand
