Abstract

Bose-Einstein condensation (BEC) of weakly interacting atomic gases was first experimentally observed in 1995 [1, 2]. In a non-interacting BEC, all atoms occupy the same single-particle wavefunction, and the total quantum state of the system is a simple product of the single-particle states. Weak interactions can be taken into account in a perturbative, mean-field fashion, and the description stays close to the product-state form.
