Algebraic Dynamics Study a Single Molecule Driven by a Time Dependent Laser Radiation Field

摘要

摘要:该文研究了含时激光辐射场驱动下的单分子系统的动力学性质。基于系统的su(1,1)⊕ h(3) 代数结构( h(3) 满足Heisenberg代数)和代数动力学方法,不仅获得了系统的解析解,而且还研究了系统的非绝热能级和几何相位。最后研究了非绝热能级和几何相位与激光辐射场频率的函数关系,展示了系统存在的共振现象以及分子共振吸收时激光辐射场频率和分子振动频率之间的漂移现象。

Abstract:The dynamical properties of a single molecule driven by a time dependent laser radiation field are researched. Based on the su(1,1)⊕ h(3) ( h(3) is Heisenberg algebra) dynamical symmetry structure of the system, the exact solutions of the system is obtained by using the algebraic dynamics method. The shift between the frequency Ω of the laser radiation field and the molecule vibration frequency ωunder resonance phenomenon is studied.
