Bose-Einstein condensation and quantum atomic sensors

My group has two thrusts.  In one effort we utilize sophisticated tools to cool atoms to temperatures less than one millionth of a degree above absolute zero. Using these tools, we explore topics ranging from superfluidity in Bose-Einstein condensates (BECs) to quantum antiferromagnetism in a spinor condensate.  In another effort we partner with engineers to build cutting edge atomic quantum sensors on-chip that can one day be mass-produced.
