CONDENSED MATTER
Quantum Condensate Gets a Fresh Squeeze
Charles Seife
Cooled to a few billionths of a degree above absolute zero, atoms in a Bose-Einstein condensate represent an extreme state of matter. But physicists have now subjected the atoms in condensates to even more outrageous ordeals, squeezing them into one-dimensional lines and two-dimensional planes. The experiments, reported in the 24 September Physical Review Letters, open the door to investigating a new regime of physics in which the rules are easier to understand.
