  • Physicists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland have proposed a recipe for turning ultracold “boson” atoms — the ingredients of Bose-Einstein condensates — into a “supersolid,” an exotic state of matter that behaves simultaneously as a solid and a friction-free superfluid.

  • A new method has been developed to directly and precisely measure a quantum property of individual atoms -- the phase shifts that result when they collide at ultracold temperatures -- in a way that is independent of the accuracy-limiting density of the atoms.

  • It is pretty easy to do a poll perhaps not well..., it is pretty hard to to ultracold STM of atomic junctions.

  • The record-breaking lows were among the latest feats of ultracold physics, the laboratory study of matter at temperatures so mind-bogglingly frigid that atoms and even light itself behave in highly unusual ways.

    Wow, that's cold! Fr Timothy Matkin 2008

  • Physicists at JILA have performed the first-ever precision measurements using ultracold molecules, in work that may help solve a long-standing scientific mystery -- whether so-called constants of nature have changed since the dawn of the universe.
