| Abstract: | he exact solutions of interface state eigenvalue problems of lattice vibrations in a monoatomic chain of symmetry A-B-A structure are investigated by use of the interface rescaling approach. The necessary and sufficient condition for the existence of such interface states is obtained exactly and analytically. |
