Resonant control of polar molecules in an optical lattice



Thomas M. Hanna, Eite Tiesinga, William F. Mitchell, Paul S. Julienne


We study the resonant control of two nonreactive polar molecules in an optical lattice site, focussing on the example of RbCs. Collisional control can be achieved by tuning bound states of the intermolecular dipolar potential, by varying the applied electric field or trap frequency. We consider a wide range of electric fields and trapping geometries, showing that a three-dimensional optical lattice allows for significantly wider avoided crossings than free space or quasi-2D geometries. Furthermore, we find that dipolar confinement induced reso- nances can be created with reasonable trapping frequencies and electric fields, and have widths that will enable useful control in forthcoming experiments.
