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 …

It is now well established that glasses feature quasilocalized nonphononic excitations—
coined “soft spots”—, which follow a universal ω 4 density of states in the limit of low …

We perform molecular dynamics simulations to investigate the effect of a glass preparation
on its yielding transition under oscillatory shear. We use swap Monte Carlo to investigate a …

It has been recently established that the low-frequency spectrum of simple computer glass
models is populated by soft, quasilocalized nonphononic vibrational modes whose …

Equilibrium sampling of the configuration space in disordered systems requires algorithms
that bypass the glassy slowing down of the physical dynamics. Irreversible Monte Carlo …

It was recently demonstrated that a simple Monte Carlo (MC) algorithm involving the swap of
particle pairs dramatically accelerates the equilibrium sampling of simulated supercooled …

Several strategies have been recently proposed in order to improve Monte Carlo sampling
efficiency using machine learning tools. Here, we challenge these methods by considering 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 …

Amorphous solids display a ductile to brittle transition as the kinetic stability of the quiescent
glass is increased, which leads to a material failure controlled by the sudden emergence of …

We start with a few concise definitions of the most important concepts discussed in this entry.
Glass transition For molecular liquids, the glass transition denotes a crossover from a …
