基于高维光晶格的超强模拟规范场研究

通过在已有的一套玻色-爱因斯坦凝聚（BEC）装置上搭建高效磁转移系统，我们将BEC转移到了具有优越optical access的区域，具备了实现各种维度的光晶格和超高分辨率原位成像的能力。在此基础上，我们拟开展基于高维光晶格的超强规范磁场的量子仿真实验研究，将利用光晶格产生超强的等效规范磁场，观察超冷原子系统在此超强场中的hofstadter butterfly能带结构，并研究此系统中的量子态和量子相变。

We have built a highly efficient magnetic transfering belt system in our Bose-Einstein condensation(BEC) apparatus. Now the BEC atoms sits in a location with superb optical access, which is ready for various type of optical lattices and high resolution in situ imaging. We plan to start the research on synthetic gauge field with high dimention optical lattice. We will generate extremely strong gauge field with allow us to observe the famous hofstadter butterfly band structure and study the novol quantum state and quantum phase transition in this system.
