论文摘要
具有可调通量的霍尔管是研究量子霍尔物理学的重要几何形状，但其在真实空间中的实验实现仍然具有挑战性。在这里，我们建议在一维光学晶格中实现带有可调通量的合成霍尔管，其合成环尺寸由原子超细态定义。我们研究通量对系统拓扑的影响并研究其淬火动力学。利用可调通量，我们展示了如何实现拓扑电荷泵送，在旋转的自旋基础上观察到有趣的电荷流量和运输。最后，我们表明，最近观察到的合成大厅管中的淬灭动力学可以用实验中存在的随机通量来解释。
Hall tube with a tunable flux is an important geometry for studying quantum Hall physics, but its experimental realization in real space is still challenging. Here, we propose to realize a synthetic Hall tube with tunable flux in a one-dimensional optical lattice with the synthetic ring dimension defined by atomic hyperfine states. We investigate the effects of the flux on the system topology and study its quench dynamics. Utilizing the tunable flux, we show how to realize topological charge pumping, where interesting charge flow and transport are observed in rotated spin basis. Finally, we show that the recently observed quench dynamics in a synthetic Hall tube can be explained by the random flux existing in the experiment.
