Previous investigation into the dynamics of a gaseous Bose-Einstein condensate has revealed a number of interesting phenomena such as solitons and vortices. The current research is designed to examine the validity of the mean-field approximation previously employed by including correlation effects using a multi-configurational approach well known in quantum chemistry. The new method will be applied to condensates in optical lattices where transitions from delocalized to localized states are known to occur.

先前对气态玻色-爱因斯坦凝聚动力学的研究揭示了许多有趣的现象，如孤子和涡旋。 目前的研究旨在检查的有效性，以前采用的平均场近似，包括使用量子化学中众所周知的多组态方法的相关效应。 新的方法将被应用到凝聚在光学晶格中的离域到本地化状态的转变是已知的发生。
