A gas of neutral atoms cooled down to near absolute zero temperature causes a phase transition called Bose-Einstein condensation, resulting in quantum condensates possessing strange properties, as exemplified by superfluidity. We investigate various phenomena exhibited by atomic Bose-Einstein condensates.
