On the Structure of the Bose-Einstein Condensate Ground State
arXiv:cond-mat/9905101 · doi:10.1103/PhysRevB.60.3044
Abstract
We construct a macroscopic wave function that describes the Bose-Einstein condensate and weakly excited states, using the su(1,1) structure of the mean-field hamiltonian, and compare this state with the experimental values of second and third order correlation functions.
