A controllable electrostatic double-well trap for cold polar molecules

We propose a novel controllable electrostatic double-well trap scheme by using two charged ring wires and two parallel transparent electrodes. The spatial distributions of the electrostatic field from the above charged wires and the charged plates are calculated. We also analyze the advantages of the proposed scheme, and discuss the loading process of cold molecules from a cold molecular beam into our trap. Our study shows that our controllable double-well trap is not only convenient to trap, manipulate and control cold polar molecules in the weak-field-seeking states, but also has the potential applications in molecule optics field，such as molecular interference, molecular entanglement, and molecular collisions, even to study the molecular BEC in the double-well trap, and so on.
