Abstract

We propose a controllable surface guiding scheme for cold polar molecules by using four charged wires embedded in the substrate and calculate the spatial distributions of the electrostatic field. We analyze the relationship between the maximum trapping electric field (including the efficient well depth) and the system parameters, and we study the straight and bent guiding efficiencies of cold polar molecules in the weak-field-seeking state by using a simple theoretical model and Monte Carlo simulation. We show that the proposed four-wire scheme can be used to realize the manipulation and control of cold polar molecules in our surface guide on a chip and form a variety of molecule optics elements.
