Physicists create Bose–Einstein condensate from ultracold polar molecules

Bose–Einstein condensates are states of matter that form when particles called bosons are cooled to temperatures that are only a fraction of a degree above absolute zero (i.e., 0 Kelvin [-460°F]).

In these states, particles occupy the same quantum state and exhibit interesting collective behaviors, essentially behaving as if they were a single "super-particle." ...
