非简谐性离子晶格在光场中的能谱动态斯塔克效应

以文献（５）在偶极近似与旋转波近似下导出的哈密顿算符（Ｈａｍｉｌｔｏｎｉｎａｎ）为基础，并以单模光频支声子与单模光场的共振耦合系统为简化模型，取得该耦合系统相互作用能谱的比较严格的解析解，同时还发现一种起源于声子－声子耦合的真空（能级）平移效应，可以预期，本文所研究的能谱将是有关晶体物质结构的又一种信息源。

Energy Spectrum of Anharmonic Ionic-Crystal Lattice in Lightfield A Dynamical Stark Effect

On the basis of Hamiltonian derived in the references under the dipole and rotating wave approximations, the energy spectrum of ionic crystal lattice vibration anharmonicly in lightfield is discussed. The energy level as the total number n of photons and optic phonons with the same mode frequency splits up into sublevels via the photon phonon and phonon phonon coupling, which would be a kind of dynamical (A.C.) Stark effect. We found a purely quantum effect: the n= 0 (vacuum) level is shifted by the interaction between phonons themselfs. It is expected that spectrum calculated might be another resource of information for crystal structure.
