=== Condensates of fermionic atoms === When [[Eric Cornell]] and [[Carl Wieman]] produced a Bose–Einstein condensate from [[rubidium]] [[atom]]s in 1995, there naturally arose the prospect of creating a similar sort of condensate made from fermionic atoms, which would form a superfluid by the BCS mechanism. However, early calculations indicated that the temperature required for producing Cooper pairing in atoms would be too cold to achieve. In 2001, Murray Holland at [[JILA]] suggested a way of bypassing this difficulty. He speculated that fermionic atoms could be coaxed into pairing up by subjecting them to a strong [[magnetic field]]. In 2003, working on Holland's suggestion, [[Deborah S. Jin|Deborah Jin]] at JILA, [[Rudolf Grimm]] at the [[University of Innsbruck]], and [[Wolfgang Ketterle]] at [[MIT]] managed to coax fermionic atoms into forming molecular bosons, which then underwent Bose–Einstein condensation. However, this was not a true fermionic condensate. On December 16, 2003, Jin managed to produce a condensate out of fermionic atoms for the first time. The experiment involved 500,000 [[potassium]]-40 atoms cooled to a temperature of 5×10<sup>−8</sup> K, subjected to a time-varying magnetic field.<ref name=":0">{{Cite journal |last1=Regal |first1=C.A. |last2=Greiner |first2=M. |last3=Jin |first3=D.S. |date=2004-01-28 |df=dmy-all |title=Observation of resonance condensation of Fermionic atom pairs|journal=Physical Review Letters |volume=92 |issue=4 |pages=040403 |doi=10.1103/PhysRevLett.92.040403 |pmid=14995356 |arxiv=cond-mat/0401554|bibcode=2004PhRvL..92d0403R |s2cid=10799388 }}</ref>
