Query: Deforming Diamond   For materials science, diamond crystals are almost unrivaled for hardness and
a range of other properties. Yet, when simply abstracting the carbon bonding
structure as a geometric bar-and-joint periodic framework, it is far from
rigid. We study the geometric deformations of this type of framework in
arbitrary dimension d, with particular regard to the volume variation of a unit
cell.
