研究了激光驱动的超冷里德伯原子在激光耦合消失极限下的一维和二维均匀晶格的静态特性。将方晶格的谱结构与线性链的谱结构进行了比较，指出了两者的异同。此外，我们采用了一种基于图论元素的方法来数值确定各种晶格几何的激光失谐相关基态。给出并讨论了链、方格和矩形格的基态。
We investigate static properties of laser-driven, ultracold Rydberg atoms confined to one- and two-dimensional uniform lattices in the limit of vanishing laser coupling. The spectral structure of square lattices is compared to those of linear chains and similarities as well as differences are pointed out. Furthermore, we employ a method based on elements of graph theory to numerically determine the laser detuning-dependent ground states of various lattice geometries. Ground states for chains as well as square and rectangular lattices are provided and discussed.
