论文摘要
我们在实验上实现了带有同质捕获的费米气体的自旋摩托晶格。该晶格是通过三个裸露原子旋转状态之间的周期性旋转原子激光耦合创建的，并且可以在合成的自旋摩肌空间中形成三角形晶格。我们证明了晶格并通过自旋和动量分辨的吸收成像探索其动力学。该平台将为合成旋转系统和拓扑带的工程提供新的机会。特别是，在两个空间维度中使用三个自旋状态将允许模拟高空间均匀性的合成磁场，这将导致支持强大的分数量子厅状态的超鼻涕Chern带。
We experimentally realize a spin-momentum lattice with a homogeneously trapped Fermi gas. The lattice is created via cyclically-rotated atom-laser couplings between three bare atomic spin states, and are such that they form a triangular lattice in a synthetic spin-momentum space. We demonstrate the lattice and explore its dynamics with spin- and momentum-resolved absorption imaging. This platform will provide new opportunities for synthetic spin systems and the engineering of topological bands. In particular, the use of three spin states in two spatial dimensions would allow the simulation of synthetic magnetic fields of high spatial uniformity, which would lead to ultra-narrow Chern bands that support robust fractional quantum Hall states.
