Coherence Times Of Bose-Einstein Condensates Beyond The Shot-Noise Limit Via Superfluid Shielding

Source: Cornell University Library 10/26/16 "We demonstrate a new way to extend the coherence time of separated Bose-Einstein condensates that involves immersion into a superfluid bath. When both the system and the bath have similar scattering lengths, immersion in a superfluid bath cancels out inhomogeneous potentials either imposed by external fields or inherent in density fluctuations due... » read more

Atom interferometers The Massachusetts Institute of Technology (MIT) has devised one of the world’s most accurate atom interferometers. Interferometry is a common measurement technique. Basically, the technology looks at electromagnetic waves. The waves are superimposed to extract information. One interferometry technology type, called an atom interferometer, utilizes the waves of ato... » read more
