Physics Professor Pioneers New Method to Image Vortices in Ultracold Gases

September 3, 2010

Physics professor David Hall and his group of undergraduate researchers have invented a new technique for examining the behavior of rotating matter at the coldest temperatures in the universe.

The method—which involves an apparatus that refrigerates atoms to billionths of a degree above absolute zero—enabled them to create the first-ever movies of vortex motion in individual Bose-Einstein condensates (BECs). And they developed the technique in Hall’s very own campus laboratory.
