Current BEC Research

We are investigating Bose-Einstein condensation in the rubidium 85 isotope. Most BEC research has been carried out in 87Rb, but 85Rb has some important differences. By changing the magnetic field we can dramatically change the self- interactions in the condensate. This allows us to produce and study a wide variety of behaviors.  These include quantum collapses and explosion of the condensate ("Bosenova") and the creation of BECs that are quantum superpositions of atoms and molecules.  The molecules formed in this process are very exotic -- more like atom Cooper pairs than traditional molecules.  We are investigating these molecules and general features of these "resonant BECs."
