A concerted experimental and theoretical investigation of Shubnikov–de Haas oscillations and the integer quantum Hall effect in thin films of CdAs leads to a new understanding of the Landau level spectrum in this archetypal Dirac semimetal under strong quantum confinement conditions. Experiments reveal an emerging =3 quantum Hall state as the film thickness is reduced, indicating an enhanced spin splitting. This is consistent with tight-binding calculations that show nonmonotonic enhancement of the factor with increasing quantum confinement.

Spin-orbit coupling breaks the Galilean invariance in materials, leading to observable many-body corrections to different transport coefficients. Here, the authors study the intrinsic contribution to anomalous Hall and spin Hall conductivities of a magnetic two-dimensional electron liquid with Rashba spin-orbit coupling. They show that both of these responses are strongly affected by electron-electron interaction. The anomalous Hall conductivity is enhanced at low carrier concentrations, while in the same regime, the sign of spin Hall conductivity is reversed.
