Spin-models of granular compaction: From one-dimensional models to random graphs
arXiv:cond-mat/0110413 · doi:10.1142/9789812795410_0003
Abstract
We discuss two athermal types of dynamics suitable for spin-models designed to model repeated tapping of a granular assembly. These dynamics are applied to a range of models characterised by a 3-spin Hamiltonian aiming to capture the geometric frustration in packings of granular matter.
