Ultracold atom

Ultracold atoms are atoms that have been cooled to temperatures just billionths of a degree above absolute zero, a feat achieved using sophisticated laser and magnetic techniques in laboratory settings. At these extremely low temperatures, atoms move so slowly that quantum mechanical properties become visible and dominant, allowing scientists to observe unusual behaviors like atoms existing in multiple states simultaneously or flowing without any friction. These ultracold atoms serve as powerful tools for fundamental physics research, helping scientists test the rules of quantum mechanics and develop technologies like quantum computers and atomic clocks.
