我们提出了一种用于弱场搜索状态下的冷极性分子的分束器，该分束器使用半嵌入基板中并夹在带电金属平行板电容器之间的 Y 形带电导线。我们展示了我们的分子分束器，并通过蒙特卡罗模拟研究了其对引导冷分子的动态分束过程。我们的研究表明，来自平均速度为每秒几百米的超音速束源的冷极性分子可以以固定的0.5/0.5分光比进行分光，并且通过对方案进行小的改动可以实现约0.03-0.97的可调分光比。
We propose a beam splitter for cold polar molecules in weak-field-seeking states that uses a Y-shaped charged wire half embedded in a substrate and sandwiched by a charged metallic parallel-plate capacitor. We demonstrate our molecular-beam splitter and study its dynamic beam-splitting process for the guided cold molecules by using Monte Carlo simulation. Our study shows that cold polar molecules from a supersonic beam source with a mean velocity of a few hundred meters per second can be split with a fixed 0.5/0.5 splitting ratio, and an adjustable splitting ratio of about 0.03-0.97 can be realized by introducing a small alteration to the scheme.
