Glassy dynamics in granular compaction
arXiv:cond-mat/9912077 · doi:10.1088/0953-8984/12/29/333
Abstract
Two models are presented to study the influence of slow dynamics on granular compaction. It is found in both cases that high values of packing fraction are achieved only by the slow relaxation of cooperative structures. Ongoing work to study the full implications of these results is discussed.
