Almost-periodic solids and the commensurability energy

Abstract:
A classification of structures of solids in terms of the almost-periodic functions is presented. The energy difference between periodic and almost-periodic structures of a solid is calculated for the one-dimensional solid with the finite-gap potential. Different applications of the result are discussed.
