| Abstract: | he exact interface states of lattice vibrations in a coupled semi-infinite monoatomic chain are investigated by use of the interface rescaling approach.The necessary and sufficient condition forthe existence of such interface states is obtained exactly and analytically.There can only exist oneinterface state under a certain coildition. |
