椭圆压缩态与Rydberg波包
Elliptical Squeezed States and Rydberg Wave Packets
摘要：
我们提出了一个最接近经典的波包本地化的角度和径向坐标和开普勒轨道上移动的理论建设。该方法产生了一个家庭的椭圆压缩态的平面库仑问题，最大限度地减少适当的不确定性关系在径向和角坐标。这些国家的时间演化的研究具有不同的半长轴和偏心率的轨道。椭圆压缩态可以用来描述由短脉冲激光在外场中激发的里德堡波包的运动，这是实验试图产生的。我们概述了该方法的扩展，包括实验中使用的碱金属原子中出现的量子缺陷的某些影响。
英文摘要：
We present a theoretical construction for closest-to-classical wave packets localized in both angular and radial coordinates and moving on a keplerian orbit. The method produces a family of elliptical squeezed states for the planar Coulomb problem that minimize appropriate uncertainty relations in radial and angular coordinates. The time evolution of these states is studied for orbits with different semimajor axes and eccentricities. The elliptical squeezed states may be useful for a description of the motion of Rydberg wave packets excited by short-pulsed lasers in the presence of external fields, which experiments are attempting to produce. We outline an extension of the method to include certain effects of quantum defects appearing in the alkali-metal atoms used in experiments.
