Dipole Trajectories in Bose-Einstein Condensates
 
 
 
Bose-Einstein condensates (BEC) are a state of matter in which supercooled atoms condense into the lowest possible quantum state.  One interesting important feature of BECs are the presence of vortices that form when the condensate is stirred with lasers.  I will discuss the behavior of these vortices, which interact with both the confinement potential and other vortices.  I will also discuss a related inverse problem in which the features of the confinement can be extracted by the propagation of vortex dipoles.
