Universally optimal sphere packing[1]

Description

A periodic sphere packing that (weakly) minimizes all completely monotonic potentials of square Euclidean distance among all periodic packings of the same density.

Cousin

  • \(A_2\) triangular lattice— The triangular lattice is universally optimal among all lattices, but has not been proven to be optimal over all periodic packings [2].
