Abstract
In this article, we present a current perspective on advances in the theoretical understanding of Bose-Einstein condensation from the standpoint of atomic, molecular and optical (AMO) physics. In AMO physics, BEC has come to be perceived both as an enabling technology, which may yield the same exquisite control of matter waves that we currently possess for light waves, and a fascinating point of contact with other branches of physics. Much of the essence of BEC in trapped-atom systems is captured in concepts which are familiar to AMO physicists, yet have rich parallels in condensed-matter, statistical, and elementary particle physics. For example, the order parameter, introduced by Landau as a unifying concept for understanding phase transitions, is manifested in dilute gas BEC as the condensate wavefunction,and it is possible to measure, photograph, and manipulate this order parameter in the laboratory.Citation
