Abstract
We discover that the apparent weight and the electrical resistance
of the randomly packed stainless steel balls exhibit unusually
slow relaxation behaviors. It is found experimentally that these
relaxations are due to structural change of packing. Simultaneous
measurements of the apparent weight and the electrical resistance
show correlated time dependence. We have also performed two
dimensional molecular dynamics simulations and studied a possible
mechanism for the slow relaxation behaviors observed in
experiments.
