Generalized Bloch states and potentials of nanotubes and other quasi-1D systems

Abstract

Bases of invariant and covariant functions for the systems with all possible line group symmetries are found. This is used to generalize the Bloch theorem to the full line group symmetry and to derive the most general forms of the emitting fields. Applications in the physics of nanotubes, polymers and other quasi-1D structures are discussed. © 2006 IOP Publishing Ltd.
