最近玻色子和费米子的超冷原子实验的迅速发展极大地促进了对强关联系统的一些基本性质的更全面的探索[1]。光学晶格中相互作用玻色子原子所表现出的从超流体到Mott{绝缘体相的转变[2]是人们观察和表征的最重要的现象之一。玻色Hubbard模型[3]与Hubbard模型具有许多相关电子的性质，其性质，包括超导性和Mott绝缘行为，已经挑战了凝聚态物理学家半个世纪。该模型可以在光学晶格上实现一维、二维和三维[4]，与电子固体相比具有巨大的优势，即粒子的动力学参数和相互作用参数之间的比率原则上是连续可调的。在实验中，需要一个捕获电位来连接
The recent rapid developments in ultra{cold{atom experiments for both bosons and fermions have greatly stimulated the fuller exploration of a number of fundamental properties of strongly correlated systems [1]. One of the most important phenomena to be observed and characterized is the transition from a superuid to a Mott{insulator phase displayed by interacting bosonic atoms in optical lattices [2]. The Bose{Hubbard model [3] shares a number of the properties of the Hubbard model for correlated electrons, whose properties, including superconductivity and Mott{insulating behavior, have challenged condensed matter physicists for half a century. This model can be realized in one, two, and three dimensions on an optical lattice [4], with the enormous advantage over electronic solids that the ratio between kinetic and interaction parameters of the particles is in principle continuously tunable. In experiments, a trapping potential is required to conne
