我们展示了一种新的实验安排，它可以以高达几千赫兹的频率旋转二维光学晶格。这种旋转晶格中的超冷原子可以用于大有效磁场下强相关系统的直接量子模拟，允许研究分数量子霍尔效应等现象。我们的安排还允许二维光学晶格的周期性动态变化，产生二维手风琴晶格。
We demonstrate a novel experimental arrangement which can rotate a 2D optical lattice at frequencies up to several kilohertz. Ultracold atoms in such a rotating lattice can be used for the direct quantum simulation of strongly correlated systems under large effective magnetic fields, allowing investigation of phenomena such as the fractional quantum Hall effect. Our arrangement also allows the periodicity of a 2D optical lattice to be varied dynamically, producing a 2D accordion lattice.
