Theory of Bloch Waves.
Abstract
The Bloch waves of the one-electron theory of electronic states in crystals are the eigenfunctions of a family of unbounded selfadjoint operators H(p) that depend holomorphically on the wave momentum p = (p1, p2, p3) elements of R cubed. H(p) has a discrete spectrum, witth corresponding complete orthonormal sequences of eigenfunctions, and it is customary to denote such a sequence by (psi sub n) (p) and speak of the Bloch waves. However, the eigenfunctions are not unique and a separate choice is required for each p. The customary definitionn therefore rests on the axiom of choice and can provide no information about the p-dependence of the Bloch waves. Some information is essential for applications. A minimal requirements is p-measurability.
