Phonons in the presence of a planar defect

P. Masri , L. Dobrzynski

We report on a rotationally invariant atomic model the possibility of two distinct branches of phonons localized at a planar defect. One of these branches falls inside the bulk band in the elastic limit and transforms in a generally well defined resonance.
