Dr. Dajun Wang, from JILA/University of Colorado, Boulder, will present, "Dipolar Collisions Between Ultracold Polar Molecules.” The successful production of near quantum degeneracy gas of polar molecules has paved the way for studying ultracold chemistry and quantum gases with strong, long-range and anisotropic interparticle dipolar interactions. Using our ultracold sample of fermionic KRb molecules, we have observed quantum threshold law governed collisions via p-wave scattering followed by near-unity probability short range chemical reactions. By turning the dipolar interactions with external electric fields, we have been able to modify the rate of these collisions dramatically. In addition, we directly observe the spatial anisotropy of the dipolar interactions manifested in measurements of the thermodynamics of the dipolar gas.
