The Bose-Einstein Condensate brings Quantum Theory to the Macroscopic Scale

The Bose-Einstein Condensate brings Quantum Theory to the Macroscopic Scale

Harald Sack
On June 5, 1995, the very first Bose-Einstein condensate was experimentally produced by Eric Cornell and Carl Wieman at the University of Colorado. A Bose–Einstein condensate (BEC) is a state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero. Under such conditions, a large fraction of the bosons occupy the lowest quantum state, at which point quantum effects become apparent on a macroscopic scale. For…
