Beam splitter for guided polar molecules with a Y-shaped charged wire
1Department of Physics, East China Normal University, Shanghai, China.
Abstract:
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.

Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied first.
