Glasslike caging with random planes
The richness of the mean-field solution of simple glasses leaves many of its features challenging to interpret. A minimal model that illuminates glass physics in the same way that the random energy model clarifies spin glass behavior would therefore be beneficial. Here we propose such a real-space model that is amenable to infinite-dimensional d→∞ analysis and is exactly solvable in finite d in some regimes.
Jamming, relaxation, and memory in a minimally structured glass former
Structural glasses form through various out-of-equilibrium processes, including temperature quenches, rapid compression (crunches), and shear. Although each of these processes should be formally understandable within the recently formulated dynamical mean-field theory (DMFT) of glasses, the numerical tools needed to solve the DMFT equations up to the relevant physical regime do not yet exist.
Gardner-like crossover from variable to persistent force contacts in granular crystals
Abstract 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 both particle positions and force networks formed under uniaxial compression. Starting from densities just above the freezing transition and for variable amounts of additional compression, we compare configurations to both their own initial state and to an ensemble of equivalent reinitialized states.
Canada’s fastest growing and decreasing municipalities from 2016 to 2021
Release date: February 9, 2022 Feedback More information PDF version Start of text box Highlights Municipalities with at least 5,000 inhabitants The municipality of Toronto, the largest in the country, had a population of almost 2.8 million people, while Montréal (1.8 million), Calgary (1.3 million), Edmonton (1 million) and Ottawa (1 million) completed the list of Canada's municipalities home to more than 1 million people. Canada continues to urbanize.

Zero-temperature glass transition in two dimensions
Abstract Liquids cooled towards the glass transition temperature transform into amorphous solids that have a wide range of applications. While the nature of this transformation is understood rigorously in the mean-field limit of infinite spatial dimensions, the problem remains wide open in physical dimensions. Nontrivial finite-dimensional fluctuations are hard to control analytically, and experiments fail to provide conclusive evidence regarding the nature of the glass transition.

Universal Microstructure and Mechanical Stability of Jammed Packings
Figure 3 Scaling of the cumulative structure function Z(r) and the cumulative force distribution G(f) in d=3 upon approaching jamming from above (a) by SS energy minimization (where e∝|Δφ|2→0 and ε=ed/2 ), and from below (b) by HS compression (where p∝|Δφ|−1→∞ ). (1a) For diminishing e , the height of the plateau (inset) converges to the isostatic value with ζ=0.53(3) . (2a) The small r<σ regime shows the “contact” scaling function Z+(x) , which agrees well with the G-RT prediction (red line).
