位相因子在光学量子拍的半经典解释中的作用

在波函数中合理地引入位相因子,用半经典方法计算了偶极矩的相关性。由此成功地解释了各种情况下观察到量子拍的可能性。计算表明:下能级分裂情况下不出现单原子量子拍,解决了以前半经典理论在解释这一点上的困难。从而使半经典理论在解释量子拍问题上经受住了QED的挑战。关键词：

THE FUNCTION OF PHASE FACTOR IN SEMICLASSICAL EXPLANATION OF OPTICAL QUANTUM BEAT

A phase factor was introduced into the wave function properly, and the correlation of the dipoles was taken into account by a semiclassical approach. Thus a successful explanation of the observability of quantum beat is obtained for various circumstances. Particularly, it has been made clear that there should be no single atom beat for the lower state splited cases, which removes the difficulty of semiclassical theory in explaining quantum beat. Therefore it has been shown that the semiclassical theory can rise to the challenge from quantum electrody namics in explaining quantum beat.
