摘要: 建立一维晶格振动声子谱的全量子理论,其哈密顿量是自动包含了Born-von-Karmann边界条件的环链量子哈密顿量,然后用不变本征算符方法简捷地求出其声子谱.

关键词: 全量子理论, 晶格振动, 不变本征算符, 声子谱

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.

Key words: full quantum theory, lattice vibration, invariant eigen-operater, phonon spectrum
