Abstract

Quantum collisions Ultracold polar molecules offer the possibility of exploring quantum gases with inter-particle interactions that are strong, long-range and spatially anisotropic. Here, Ni et al. report the experimental observation of dipolar collisions in an ultracold gas of fermionic 40K87Rb molecules. For modest values of an applied electric field, they observe a dramatic increase in the loss rate due to ultracold chemical reactions.
