An exotic quantum state that had previously appeared only under conditions of astonishing cold has made its room-temperature debut, reports an international team of scientists. In related experiments, other researchers have produced a similar state in different, still-chilly materials but claim that their experiments will lead to room-temperature versions as well.
The new findings, unveiled in independent reports in the Sept. 28 Nature, reveal a bizarre new branch of an already exotic family of quantum states of matter known as Bose-Einstein condensates.
