Bose–Einstein condensate
A Bose–Einstein condensate (BEC) is a state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero (that is, very near 5000000000000000000♠0 K or 5000000000000000000♠−273.15 °C). Under such conditions, a large fraction of bosons occupy the lowest quantum state, at which point macroscopic quantum phenomena become apparent.This state was first predicted, generally, in 1924–25 by Satyendra Nath Bose and Albert Einstein.
