Nonlinear Structures and Dynamics in the Bose Condensate

先前对气态玻色-爱因斯坦凝聚体动力学的研究揭示了许多有趣的现象，如孤子和漩涡。目前的研究旨在通过使用量子化学中众所周知的多构型方法包括相关效应来检验以前采用的平均场近似的有效性。新方法将应用于光晶格中的凝聚体，其中已知会发生从离域到局域状态的转变。

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.
