一维晶格振动声子谱的全量子理论和“不变量本征算符”方法

The full quantum theory of the phonon spectrum for 1-dimensional lattice and the method of the 'invariant eigen-operator'

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.

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.
