In the context of experimental advances in realizing artificial magnetic fields in quantum gases, feasible schemes were discussed to extend measurements of Hall voltage, with a focus on interacting flux ladders. Characteristic zero crossings and remarkable robustness of Hall voltage were observed, unaffected by interaction strengths, particle fillings, and ladder geometries, in contrast to Hall polarization. Additionally, site-resolved Hall responses were investigated in spatially inhomogeneous quantum phases.
YIn 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.
