摘要
利用解析方法描述了相干瞬态量子体系中不同类型的量子干涉效应,分别讨论了光学干涉与量子干涉所起的作用,分析了在时域对称光场作用下,几何相位在量子干涉效应中所扮演的角色,从理论上证明了通过适当改变抽运场脉冲面积,可实现对几何相位的测量.同时研究也发现利用啁啾抽运场可以实现对量子干涉效应的有效控制.
We present the analytic expressions for different types of quantum interference effects in coherent instantaneous state quantum system, and discuss the behaviors of the optics and quantum interference, respectively. The important role that the geometrical phase plays in quantum interference is analyzed in detail for the first time. It is demonstrated theoretically that the measurement of the geometrical phase can be realized by appropriately choosing the pulse area of the pump field. The valid control of the quantum interference is achieved by manipulating the chirped pump field.
