| 摘 要： | 以时域对称光场作用下的二能级原子系统为模型, 细致地研究了缀饰态中动力学相位和几何相位的表现形式和分布状态. 利用量子干涉效应, 在理论上提出了实现测量几何相位分布的新方法. 这种测量方法克服了核磁共振和光子回波技术的不足之处, 阐述了测量方法和物理机理.

| Abstract: | Based on the model of the interaction between a light field and a two-level atomic system and the quantum interference effect,the characteristic and distribution of the geometric phase is investigated in detail.We present a new scheme for measuring the geometric phase of the prepared states in theory.The scheme is that controlling the pulse area of the strong pump field accurately,the geometric phase can be measured directly.The new scheme overcomes the disadvantage of the nuclear-magnetic-resonance and pho... |
