Instability cascades in crumpling mylar sheets follow a log-Poisson statistic
Stefan Boettcher, Paula A. Gago
The process of aging following a hard quench into a glassy state is characterized universally, for a wide class of materials, by logarithmic evolution of state variables and a powe…
Density Fluctuations in Granular Piles Traversing the Glass Transition: A Grain-Scale Characterization of the Transition via the Internal Energy
Paula A Gago, Stefan Boettcher
The transition into a glassy state of the ensemble of static, mechanically stable configurations of a tapped granular pile is explored using extensive molecular dynamics simulation…
A numerical characterisation of unconfined strength of weakly consolidated granular packs and its effect on fluid-driven fracture behaviour
Paula A. Gago, Charalampos Konstantinou, Giovanna Biscontin +1
Soft or weakly-consolidated sand refers to porous materials composed of particles (or grains) weakly held together to form a solid but that can be easily broken when subjected to s…
Extremal fluctuations driving the relaxation in glassy energy landscapes
Stefan Boettcher, Paula A. Gago, Paolo Sibani
Cooperative events requiring anomalously large fluctuations are a defining characteristic for the onset of glassy relaxation across many materials. The importance of such intermitt…
Universal Features of Annealing and Aging in Compaction of Granular Piles
Paula A. Gago, Stefan Boettcher
We explore the compaction dynamics of a granular pile after a hard quench from a liquid into the glassy regime. First, we establish that the otherwise athermal granular pile during…
Structural Evolution of Granular Systems: Theory
Clara C. Wanjura, Paula Gago, Takashi Matsushima +1
A general theory is developed for the evolution of the cell order (CO) distribution in planar granular systems. Dynamic equations are constructed and solved in closed form for seve…
