Many-Body Theory of Dilute Bose-Einstein Condensates with Internal Degrees of Freedom
arXiv:cond-mat/0008189 · doi:10.1103/PhysRevA.63.013601
Abstract
The Bogoliubov theory of weakly interacting bosons is generalized to Bose-Einstein condensates with internal degrees of freedom so that a single effective Hamiltonian produces various many-body ground states or metastable spin domains and the corresponding collective modes on an equal footing.
