AI 中文摘要
多种相互作用会扰动(或位移)第1族原子中核自旋与单个价电子之间的超精细耦合。此前研究提供了一种估算该位移的方法,适用于与其他原子或分子的非反应性长程碰撞,还将其扩展至估算静电场导致的位移。我们进一步将该方法扩展,以估算邻近导电表面导致的位移,并通过数值计算更新其所用特征能量值,改进所有这些估算。我们研究如何通过标度论证估算这些能量,并提出如何将该方法适配至其他应用。研究结果与蒸汽池的压力位移、斯塔克位移及纳米尺度器件的壁位移相关。
英文摘要
Many interactions perturb (or shift) the hyperfine coupling in group-1 atoms between their nuclear spin and single valence electron. Previous work provided an approach to estimate this shift for non-reactive collisions with other atoms or molecules at long range, and extended it to estimate the shift from static electric fields. We further extend this approach to estimate the shift due to a nearby conductive surface, and improve all these estimates by numerically computing updated values for the characteristic energies they use. We investigate how to estimate these energies by scaling arguments, and suggest how to adapt the approach to other applications. The results are relevant to pressure shifts in vapor cells, Stark shifts, and wall shifts in nanoscale devices.
