提出了一种利用两个带电球形电极实现冷极性分子囚禁的光学静电阱方案，并计算了相应的电场分布和ND3分子的Stark囚禁势.我们还提出了一个理想的方案来实现对弱寻场态冷极性分子的有效加载，模拟结果表明最大加载效率可达14%。此外，我们简要讨论了我们提出的陷阱方案在研究冷极性分子的光势蒸发冷却和静电表面陷阱中的一些潜在应用。
We propose an optically accessible electrostatic trap scheme to confine cold polar molecules by using two charged spherical electrodes, and we calculate the corresponding electric field distribution and the Stark trapping potential for ND3 molecules. We also propose a desirable scheme to realize an efficient loading of cold polar molecules in weak-field-seeking states, and our simulated results show that the maximal loading efficiency can reach ∼14%. In addition, we briefly discuss some potential applications of our proposed trap scheme in the studies of optical-potential evaporative cooling and electrostatic surface traps for cold polar molecules.
