Jamming in granular hopper flow
James W. Landry, Gary S. Grest
Large-scale three dimensional molecular dynamics simulations of hopper flow are presented. The flow rate of the system is controlled by the width of the aperture at the bottom. As…

Discrete element simulations of stress distributions in silos: crossover from two to three dimensions
James W. Landry, Gary S. Grest, Stephen J. Plimpton
The transition from two-dimensional (2D) to three-dimensional (3D) granular packings is studied using large-scale discrete element computer simulations. We focus on vertical stress…

Dynamics of a Complex Quantum Magnet
J. W. Landry, S. N. Coppersmith
We have computed the low energy quantum states and low frequency dynamical susceptibility of complex quantum spin systems in the limit of strong interactions, obtaining exact resul…
