Bose–Einstein condensate

Schematic Bose-Einstein Condensation versus temperatur an the energy diagram

A Bose–Einstein condensate (BEC) is a state o maiter o a dilute gas o bosons cuiled tae temperaturs very close tae absolute zero (that is, very near 5000000000000000000♠0 K or 5000000000000000000♠−273.15 °C). Unner sic condeetions, a lairge fraction o bosons occupy the lawest quantum state, at which pynt macroscopic quantum phenomena acome apparent. It is formed bi cuiling a gas o extremely law density, aboot ane-hunder-thoosandt the density o normal air, tae ultra-law temperaturs.
