A primary theme of our current work is to use the properties of polar molecules for unique types of leverage on our research problems. Compared to atoms, polar molecules have extremely large electric polarizability arising from the small energy spacing between rotational states. This property has up to now been largely unexploited for fundamental studies and is at the heart of most of our experiments. We use it both as a means of amplifying tiny symmetry-violating effects within the molecules and as a means for manipulating the external properties of the molecules.
