Contents
Model lattices consisting of balls connected by central-force springs provide much of our understanding of mechanical response and phonon structure of real materials. Their stability depends critically on their coordination number z . d -dimensional lattices with z = 2 d are at the threshold of mechanical stability and are isostatic. Lattices with...
