Effects of compression on the vibrational modes of marginally jammed solids
Matthieu Wyart, Leonardo E. Silbert, Sidney R. Nagel +1
Glasses have a large excess of low-frequency vibrational modes in comparison with most crystalline solids. We show that such a feature is a necessary consequence of the weak connec…
Reply to "Comment on `Jamming at zero temperature and zero applied stress: The epitome of disorder' "
C. S. O'Hern, L. E. Silbert, A. J. Liu +1
We answer the questions raised by Donev, Torquato, Stillinger, and Connelly in their "Comment on "Jamming at zero temperature and zero applied stress: The epitome of disorder.' " W…
Temporally heterogeneous dynamics in granular flows
L. E. Silbert
Granular simulations are used to probe the particle scale dynamics at short, intermediate, and long time scales for gravity driven, dense granular flows down an inclined plane. On…
Vibrations and diverging length scales near the unjamming transition
L. E. Silbert, A. J. Liu, S. R. Nagel
We numerically study the vibrations of jammed packings of particles interacting with finite-range, repulsive potentials at zero temperature. As the packing fraction is lowered…
