WebRapidly grown disk packings display occasional vacancies within the crystalline grains; no comparable voids of such distinctive size have been found in the random sphere packings. "Rattler" particles free to move locally but imprisoned by jammed neighbors occur in both the disk and sphere packings. http://fhs.mycpanel.princeton.edu/fhspapers/fhspaper195.pdf

Sparse Hard-Disk Packings and Local Markov Chains

Webremainder are not jammed but are locally imprisoned by their neighbors (the rattlers). If there is no jammed backbone, then the packing is unjammed. Note that, unless specified otherwise, packings are typically characterized (e.g., in order maps) while including rattlers. The family of jammed packings is conveniently described via WebWe propose locally stable sparse hard-disk packings, as introduced by Böröczky, as a model for the analysis and benchmarking of Markov-chain Monte Carlo (MCMC) algorithms.

WebLocally jammed: Each particle in the system is locally trapped by its neighbors, i.e., it cannot be translated while ﬁxing the positions of all other particles. ... To begin, it is useful and instructive to classify simple ordered packings of disks or spheres into the above jamming categories. One can create such packings by placing disks or ... WebThe packings occasionally contain monovacancies and trapped but unjammed “rattler” disks. The latter appear to be confined to the grain boundaries. The linear shear fractures preserve bond orientational order, but disrupt translational order, within the …
