Memory formation in jammed hard spheres
Patrick Charbonneau, Peter Morse
Liquids equilibrated below an onset density share similar inherent states, while above that density their inherent states markedly differ. Although this phenomenon was first report…
Predicting plasticity in disordered solids from structural indicators
D. Richard, M. Ozawa, S. Patinet +16
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…
Two classes of events in sheared particulate matter
Peter K. Morse, Sven Wijtmans, Merlijn van Deen +2
Under shear, a system of particles changes its contact network and becomes unstable as it transitions between mechanically stable states. For hard spheres at zero pressure, contact…
A simple random matrix model for the vibrational spectrum of jammed packings
E M Stanifer, P K Morse, A A Middleton +1
To better understand the surprising low-frequency vibrational modes in structural glasses, we study the spectra of a large ensemble of sparse random matrices where disorder is cont…
