Summary:
forces in jammed solids
¥Solid is uniform, but forces are heterogeneous
¥Forces grow exponentially with distance from source [Moukarzel Phys. Rev. Lett. 81, 1634
(1998)]
¥They can propagate asymmetrically, unlike an elastic
solid
¥These properties arise from their minimal
connectivity, which requires a delicate balance of
stresses.
