Bose-Einstein Condensate runs circles around magnetic trap

From PhysOrg.com [first published: September 07, 2005]

Physicists at the University of California, Berkeley, have the universe's coldest substance running in circles.

The UC Berkeley team has created a Bose-Einstein condensate of rubidium atoms and nudged it into a circular racetrack 2 millimeters across, creating a particle storage ring analogous to the accelerator storage rings of high energy physics. This ring, the first to contain a Bose-Einstein gas, is full of cold particles at a temperature of only one-millionth of a degree above absolute zero, travelling with energies a billion trillion times less than the particles in a high-energy storage ring.
