What is the Bose-Einstein-condensate?

Answer 1

A Bose Einstein Condensate is a state of matter that occurs when matter is cooled to its lowest energy state, the fermions in the matter, normally excluded from each other due to the exclusion principle, collapse onto each other to form Cooper pairs and achieve a bosonic behavior

Answer 2

Bose-Einstein condensate is a state of matter formed at ultra-low temperatures when all particles in a gas phase collapse into the lowest quantum state. It exhibits unique quantum effects like superfluidity and coherence on a macroscopic scale. It was first predicted by Satyendra Nath Bose and Albert Einstein in the 1920s.
