Glasses are materials that lack a crystalline microstructure and long‐range atomic order.
Instead, they feature heterogeneity and disorder on superstructural scales, which have …

Amorphous solids lack long-range order. Therefore identifying structural defects—akin to
dislocations in crystalline solids—that carry plastic flow in these systems remains a daunting …

Glassy solids exhibit a wide variety of generic thermomechanical properties, ranging from
universal anomalous specific heat at cryogenic temperatures to nonlinear plastic yielding …

A remarkable feature of disordered solids distinct from crystals is the violation of the Debye
scaling law of the low-frequency vibrational density of states. Because the low-frequency …

ABSTRACT A hallmark of structural glasses and other disordered solids is the emergence of
excess low-frequency vibrations on top of the Debye spectrum DDebye (ω) of phonons (ω …

We study a recently introduced and exactly solvable mean-field model for the density of
vibrational states D (ω) of a structurally disordered system. The model is formulated as a …

Plastic deformation in amorphous solids is known to be carried by stress-induced localized
rearrangements of a few tens of particles, accompanied by the conversion of elastic energy …

Nonphononic vibrations originating from disordered structures have garnered significant
attention as a fundamental feature of glasses that distinguishes them from crystals. Recently …

It has been widely accepted that the plastic events of amorphous solids after mechanical
yield belong to a highly correlated avalanche state. However, whether the plastic events …

Soft, quasilocalized excitations (QLEs) are known to generically emerge in a broad class of
disordered solids and to govern many facets of the physics of glasses, from wave …
