论文摘要
在实现量子气体中人工磁场的实验进步的背景下，我们讨论了可行的方案，以将霍尔极化的测量结果扩展到对霍尔电压的研究，从而与固态系统直接进行比较。具体而言，对于相互作用的通量梯子的范式示例，我们报告了特征性的零交叉点和关于相互作用强度，粒子填充物和梯子几何形状的霍尔电压的显着鲁棒性，这在霍尔极化中是无法观察的。此外，我们研究了空间不均匀量子相的位置分辨大厅反应。
In the context of experimental advances in the realization of artificial magnetic fields in quantum gases, we discuss feasible schemes to extend measurements of the Hall polarization to a study of the Hall voltage, allowing for direct comparison with solid state systems. Specifically, for the paradigmatic example of interacting flux ladders, we report on characteristic zero crossings and a remarkable robustness of the Hall voltage with respect to interaction strengths, particle fillings, and ladder geometries, which is unobservable in the Hall polarization. Moreover, we investigate the site-resolved Hall response in spatially inhomogeneous quantum phases.
