Editing Bose–Einstein condensate (section)

=== Applications ===

In 1999, Danish physicist [[Lene Hau]] led a team from [[Harvard University]] which [[Slow light|slowed a beam of light]] to about 17 meters per second{{Clarify|date=January 2010|reason=group velocity and not actual velocity?}} using a superfluid.<ref>{{cite web | last = Cromie | first = William J. | title = Physicists Slow Speed of Light | website = The Harvard University Gazette | date = 18 February 1999 | url = http://news.harvard.edu/gazette/1999/02.18/light.html | access-date = 26 January 2008 }}</ref> Hau and her associates have since made a group of condensate atoms recoil from a light pulse such that they recorded the light's phase and amplitude, recovered by a second nearby condensate, in what they term "slow-light-mediated atomic matter-wave amplification" using Bose–Einstein condensates.<ref name=Ginsberg:2007/>

Another current research interest is the creation of Bose–Einstein condensates in microgravity in order to use its properties for high precision [[Atom interferometer|atom interferometry]]. The first demonstration of a BEC in weightlessness was achieved in 2008 at a [[Fallturm Bremen|drop tower]] in Bremen, Germany by a consortium of researchers led by [[Ernst M. Rasel]] from [[Leibniz University Hannover]].<ref>{{Cite journal|last1=Zoest|first1=T. van|last2=Gaaloul|first2=N.|last3=Singh|first3=Y.|last4=Ahlers|first4=H.|last5=Herr|first5=W.|last6=Seidel|first6=S.

In 1970, BECs were proposed by [[Emmanuel David Tannenbaum]] for anti-[[stealth technology]].<ref>{{cite arXiv | last=Tannenbaum| first=Emmanuel David | title=Gravimetric Radar: Gravity-based detection of a point-mass moving in a static background| year=1970| eprint=1208.2377| class=physics.ins-det}}</ref>
