A group at the University of Colorado and the National Institute of Standards and Technology in Boulder has serendipitously created two Bose-Einstein condensates--each one a crowd of atoms in a single quantum state--in a supercooled magnetic trap. Their cooling technique worked directly on only one of the condensates, but the other one cooled "sympathetically," which suggests that the strategy could be used to condense hard-to-cool atoms.
