Question

give one unique property of bec

Answer 1

This property gives rise to other quantum mechanical effects like the Josephson-Effect. A Josephson-Effect always occurs when two macroscopic quantum objects are separated by a “weak link”. A “weak link” is a barrier that is high enough, that no particle of the two condensates could cross it in the classical picture but low enough, that a fraction of the condensate can tunnel through it in the quantum mechanical picture.
