#### We have made available several computer codes used in our research projects related to disordered packings of hard spheres and ellipsoids in low dimensions and sphere packings in high dimensions.

- An animation of the LS algorithm packing a system of 100 monodisperse disks (August 18th, 2014) The Lubachevsky-Stillinger molecular dynamics algorithm is used to produce a dense packing of monodisperse disks within a squarefundamental cell with periodic boundary conditions. The dimensionless growth rate is 0.01. The initial condition was generated via RSA at a packing fraction of 0.10
- An animation of the TJ algorithm packing a system of 100 monodisperse disks (August 18th, 2014) The Torquato-Jiao (“TJ”) sphere packing protocol is used to produce a collectively-jammed packing of 100 monodisperse spheres inside a fixed square fundamental cell with periodic boundary conditions. The initial condition was generated via RSA at a packing fraction of 0.10
