TL;DR: This work considers the adiabatic evolution of glassy states under external perturbations, and finds that close to the dynamical transition, glasses undergo a Gardner transition after an infinitesimal perturbation.

TL;DR: In this article, the effects of temperature and bond perturbations on the non-equilibrium dynamics of spin glasses have been investigated and the observed memory phenomena were found to be consistent with predictions from the ghost domain scenario of the droplet scaling model.

TL;DR: It is found that the intrastate shear modulus, which corresponds to the plateau modulus measured in linear viscoelastic measurements, strongly depends on temperature and vanishes continuously when the temperature is increased beyond the glass temperature.

TL;DR: By extensive numerical simulations on a hard sphere glass under quasistatic shear at finite temperatures, it is shown that above the so-called Gardner transition density, the elasticity breaks down, the stress relaxation exhibits slow, and ageing dynamics and the apparent shear modulus becomes protocol-dependent.

TL;DR: This study provides a unified framework for understanding elasticity, plasticity, yielding, and jamming in amorphous solids in glasses by exhaustively map out their stability and reversibility under volume and shear strains using extensive numerical simulations.
