Solvable models of Bose-Einstein condensates: a new algebraic Bethe ansatz scheme
arXiv:cond-mat/0211249 · doi:10.1063/1.1605495
Abstract
A new algebraic Bethe ansatz scheme is proposed to diagonalise classes of integrable models relevant to the description of Bose-Einstein condensates in dilute alkali gases. This is achieved by introducing the notion of Z-graded representations of the Yang-Baxter algebra.
