But what happens to the QHE in three dimensions (3D)? Experiments over the past 40 years showed that some of the remarkable physics of the QHE, in particular plateau-like Hall conductivities σxy accompanied by minima in the longitudinal resistivity ρxx, can also be found in 3D materials. However, since typically ρxx remains finite and a quantitative relation between σxy and the conductance quantum e2/h could not be established, the role of quantum Hall physics in 3D remains unsettled. Following a recent series of exciting experiments, the QHE in 3D has now returned to the center stage. Here, we summarize the leap in understanding of 3D matter in magnetic fields emerging from these experiments.
