【Abstract】 The exact solutions of interface state eigen 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 statesis is obtained exactly and analytically.更多还原
