One of the fundamental questions in the study of ultracold polar molecules is “what happens when two molecules collide at ultracold temperatures?” Knowing whether the molecules undergo chemical reactions, form long lived complexes, change internal state, or bounce off each other carries important implications which will guide future research directions. Our recent experiment explores this...

Ultracold molecules have been proposed as a rich resource for many applications ranging from precision measurements and quantum metrology to quantum simulation and quantum information processing. The benefits of molecules in all these applications arise from the many internal degrees of freedom in a molecule. For example, even with the simplest diatomic molecules, one has...
