Studying Bose-Einstein Superatoms |

| NIST physicist Deborah Jin aligns an infrared laser for a magneto optical trap as part of a JILA project to create "superatoms." The trap is used to collect 1 billion rubidium atoms under ultrahigh vacuum. The atoms are then sent to a second trap under even higher vacuum and cooled to only 100 nanoKelvin (billionths of a degree) above absolute zero. the result is a so called "Bose Einstein condensate" or superatom in which a large number of atoms behave in unison. This allows JILA scientists to study details of atomic behavior that normally occur for single atoms in the 1/10 nanometer scale, at a much larger, more observable scale of 10 micrometers. JILA is jointly operated by NIST and the University of Colorado. |
