Electrostatics in action: controlling cold collisions of polar molecules — •John L. Bohn — JILA, University of Colorado, Boulder, CO 80309

One of the most impressive developments to come out of the study of ultracold atomic gases is the ability to influence scattering by applying a suitable magnetic field. In this talk I will describe how ultracold heteronuclear molecules will afford even greater opportunities to control scattering, because of their dipole moments. Indeed, applying combined electric and magnetic fields can alter collision cross sections and branching ratios by orders of magnitude. I will show how this is important to the basic problem of creating and handling cold molecules, as well as to applications such as control over chemical reactions.
