Phys. Rev. A 76, 043604 (2007) [25 pages]Cold polar molecules in two-dimensional traps: Tailoring interactions with external fields for novel quantum phasesReceived 4 June 2007; published 3 October 2007 We discuss techniques to engineer effective long-range interactions between polar molecules using external static electric and microwave fields. We consider a setup where molecules are trapped in a two-dimensional pancake geometry by a far-off-resonance optical trap, which ensures the stability of the dipolar collisions. We detail how to modify the shape and the strength of the long-range part of interaction potentials, which can be utilized to realize interesting quantum phases in the context of cold molecular gases. © 2007 The American Physical Society URL:
