Below Absolute Zero -- What Does Negative Temperature Mean?
Can you really make a system which has a temperature below absolute zero? From the Usenet Physics FAQ.
A developer and supplier of Bose-Einstein condensates (BEC) and cold atom devices, instruments and systems.
NIST - Atomic Physics Division - Laser Cooling and Trapping Group
This department of the National Institute of Standards and Technology studies the physics of laser cooling, electromagnetic trapping, and other radiative manipulation of neutral atoms and dielectric particles. Home of 1997 Nobel Prize winner William D. Phillips, whose team has cooled atoms to less than a millionth of a degree above absolute zero.
The Nobel Prize in Physics 1997
This includes the press release of the Nobel Committee for the prize given to Steven Chu, Claude Cohen-Tannoudji, and William D. Phillips, for development of methods to cool and trap atoms with laser light.
