Press releases from the National Institute of Standards and Technology and explanations of the work on Bose-Einstein condensates which won the Nobel Prize.

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.

A detailed links list of about 50 research groups around the world, with an immense list of subject links, as well. From the Laser Physics Group at Umeå University, Sweden.

Using lasers to trap and cool molecules for study. Nobel Prize for Chu, Phillips, and Cohen-Tannoudji.

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.
