Experimental Studies of Atoms in Confined Spaces (Physics)

腔QED研究正在继续进行，以研究被限制在两个平面镜之间非常狭窄的空间内的原子的性质。在这种情况下，能级和辐射率被原子和金属边界之间的相互作用改变，有时是戏剧性的。现在计划用光谱学测量原子被放置在通道内定义良好的位置并随后激发成高度极化的里德伯格态时能级的范德华位移。这个位置是利用激光驻波产生的力来操纵的；原子被困在以静止水的裸体为中心的光学势垒的最低振动量子态中。

Cavity QED investigations are being continued into the properties of atoms confined to a very narrow space between two plane mirrors. In this situation energy levels and radiation rates are modified, sometimes dramatically, by the interaction between the atom and the metallic boundaries. It is now planned to measure spectroscopically the van der Waals shifts of the levels when atoms are placed at well defined locations within the channel and subsequently excited into a highly polarizable Rydberg state. The position is manipulated using the force produced by a standing wave of laser light; the atoms are trapped in the lowest vibrational quantum states of the optical potential wells centered on the nudes of the standing water.
