Abstract:
A cell-cluster analysis is described for a system of interacting rigid disks on a close-packed lattice containing a coincidence boundary. The relative stability of this system is compared to the defect-free hexagonal lattice. Through second order the authors have obtained a linearized polytope bound to Q2. The complexity of the lattice subfigures precludes carrying the analysis beyond second order. It is suggested that near close packing a coincidence boundary may locally stabilize a lattice. Author
