里德伯原子中特定角动量态的产生和探测是量子信息处理领域的重大进展。探测碱金属原子中的高角动量态是困难的，因为它们在能量上几乎是简并的。我们提出了使用太赫兹频率半周期脉冲（HCPs）检测这些状态的理论结果。在n=15,l=0，…利用基于栅格的赝势方法研究了氢和铯的14个态。结果表明，HCP重分布是一种可靠的区分角动量里德伯态的方法。
The creation and detection of specific angular momentum states in Rydberg atoms is a significant advance in quantum-information processing. Detection of high angular momentum states in alkali-metal atoms is difficult because they are nearly-degenerate in energy. We present theoretical results on the detection of such states using terahertz-frequency half-cycle pulses (HCPs). Calculations are done for n=15,l=0,...,14 states in hydrogen and cesium using a grid-based pseudopotential method. Our results indicate that HCP redistribution is a reliable method of distinguishing angular momentum Rydberg states.
