Local modes in the diatomic chain

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

The equation for the determination of local modes is developed by the method of Green's functions. The problem is solved by the transformation of the displacements and the introduction of frequency-dependent mass. In this way even a case of a general defect in the diatomic chain with nearest neighbours' interaction is converted into a monoatomic chain analysis for which the method of Green's functions has been developed. The basic relations of this method are given.
