New methods for applying the symmetry theory of stereoregular polymers for quantum-mechanical modelling of photovoltaic type materials

Abstract

It is well-known, that the detailed experimental and theoretical investigation of basic structural and physical properties of different types of carbon nano - tubes plays a role of continuously increasing importance in the whole condensed matter physics, because of the very promising experimental investigation results about solar energy applications, too. Among them, the very powerful symmetry analysis methods based on the representation theory of symmetry groups of the ideal, and infinitesimally long discrete chain-type subsystems accepted as the relevant ones. The adequate quantum mechanical analysis of the collective elementary excitations was developed by applications of the representation theory of line groups. In order to apply our own earlier theoretical results in this contemporary research area, we decided to extend them in more details, in order to give new, original significant contributions to the theoretical modeling of the basic optical properties of the stereoregular polymers and carbon nanotubes at the quantum-level.
