Effective quantum number for describing nanosystems

Abstract

An enormous variety of quantum nanoobjects and nanosystems calls for the development of new approaches to their description and parametrization. Corresponding methods should be simple, universal enough and ensuring the retention of essential part of information at small number of parameters. A universal effective quantum number was introduced earlier and successfully used for describing centrally symmetric systems. But in most cases nanosystems own a lower symmetry. In the present article we generalize and adapt this method for such systems.
