Bose–Einstein condensates

Bose-Einstein condensates (BEC) are a state of matter that occurs at extremely low temperatures, close to absolute zero (0 Kelvin or -273.15 degrees Celsius). In this state, a group of atoms is cooled to such an extent that they occupy the same quantum state, essentially behaving as a single quantum entity. The phenomenon is named after two physicists, Satyendra Nath Bose and Albert Einstein, who described it in the early 20th century.
