摘要：

In this article, we present a tutorial discussion of the coherence properties of Bose-Einstein condensates. We use a formalism which is similar to the one used in quantum optics. We describe within the variational approximation the question of the relative phase of two condensates. To evaluate the structure factors of a condensate, we briefly review the Bogolubov approach and describe light scattering off a condensate using the linear response formalism. Finally, we study the effect of atomic interactions on the condensate's dynamics. (C) 2001 Academie des sciences/Editions scientifiques ct medicales Elsevier SAS.
