| Abstract: | The full quantum theory of the phonon spectrum for 1-dimensional lattice is proposed,whose Hamiltonian is quantum mechanical ring Hamiltonian with Born-von-Karmann boundary condition.The method of `invariant eigen-operator' to derive its phonon spectrum is applied. |
| Keywords: | full quantum theory lattice vibration invariant eigen-operater phonon spectrum |
