1/29/92 What is absolute zero? Temperature is a physical quantity which gives us an idea of how hot or cold an object is. The temperature of an object depends on how fast the atoms andmolecules which make up the object can shake, or oscillate. As...Using lasers to trap and cool molecules for study. Nobel Prize for Chu, Phillips, and Cohen-Tannoudji.

Steven Chu, former Bell Labs researcher, wins Nobel in physics The idea of using lasers to trap and cool molecules for study began over a lunchtable conversation at Bell Labs in Holmdel, N.J. more than 10 years ago. Today, because of his idea, former Bell Labs researcher Steven Chu is...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.
