Packing Hard Spheres on Lattices
by
,Amphithéâtre Léon Motchane
IHES
Probability and analysis informal seminar
In this joint talk we focus on some recent results on packings of identical hard spheres of diameter D on 2D- and 3D- lattices and graphs (a unit triangular lattice A2, a unit honeycomb graph H2, a unit square lattice Z2, a unit cubic lattice Z3). In particular, we will use connections with the algebraic number theory. Our results identify dense-packing configurations and their random "perturbations" (extreme Gibbs distributions) describing high-density "pure phases" of the hard-sphere lattice model of statistical mechanics.
