Atom interferometry promises great accuracy in measuring changes in atomic energy. We are focusing on two measurements in particular. First, by shining a Stark beam only on one packet of the interferometer, we can measure the fine constant through the change in the packet’s phase  as compared to the non-illuminated one. Second, by bouncing the free-falling packets indepently of one another, we can measure the difference in the packets’ interactions to gravity when they are separated by a small distance. Our group are exploring both of the topics using both a linear waveguide and a cylindrically-symmetric waveguide with BEC atom interferometry.
