Statistical and dynamical equivalence of different elementary cells

Abstract

The method of achievement statistical and dynamical equivalence between rectangular and lower symmetry structures is proposed. The importance of this method is essential for analysis of broken symmetry structures (especially nanostructures). The method was applied to Heisenberg ferromagnet in Bloch's approximation. Although the method is not universal for triclinic structures, the practical field of its application is relative widely. If we deal with monoclinic structures method of equivalence is applicable always. Copyright © 2007 American Scientific Publishers All rights reserved.
