Ultracold Molecules: Collisions and Interactions

It wasn't so long ago, that collisions of molecules in ultracold gases (say, microKelvin or less) were merely a theorist's pipe dream. This situation has changed recently, with laboratories all over the world reporting exciting and sometimes unexpected results. This talk will address topics of current interest and their basic underlying physics, to give the Student a basis from which to explore further. Topics will include such apparently moral judgements as "good collisions" and "bad collisions," along with shielding of collisions, coherent control, "sticky" collisions, and collisional decoherence.
