Note: This Perspective offers a progress report for the Simons collaboration “Cracking the
Glass Problem,” of which the authors are some of the principal investigators. While the …

The criticality of the jamming transition responsible for amorphous solidification has been
theoretically linked to the marginal stability of a thermodynamic Gardner phase. While the …

Liquids equilibrated below an onset condition share similar inherent states, while those
above that onset have inherent states that markedly differ. Although this type of materials …

Jamming criticality defines a universality class that includes systems as diverse as glasses,
colloids, foams, amorphous solids, constraint satisfaction problems, neural networks, etc. A …

Jamming is an emergent phenomenon wherein the local stability of individual particles
percolates to form a globally rigid structure. However, the onset of rigidity does not imply that …

A novel form of amorphous matter characterized by marginal stability was recently
discovered in the mean-field theory of structural glasses. Using this approach, we provide …

We report experimental evidence of a Gardner-like crossover from variable to persistent
force contacts in a two-dimensional bidisperse granular crystal by analyzing the variability of …

We present a universal characterization of stress correlations in athermal systems, across
crystalline to amorphous packings. Via numerical analysis of static configurations of particles …

It is widely accepted that structural glasses and disordered crystals exhibit anomalies in their
thermal, mechanical and acoustic properties as manifestations of the breakdown of the long …

We analyze the fluctuations in particle positions and interparticle forces in disordered
crystals composed of jammed soft particles in the limit of weak disorder. We demonstrate …
