We investigate the effect of surface disorder on the chiral surface states of a three-dimensional quantum Hall system. Utilizing a transfer matrix method, we find that the localization length of the surface state along the magnetic field decreases with the disorder strength in the weak disorder regime, but increases anomalously in the strong disorder regime. In the strong disorder regime, the surface states mainly locate at the first inward layer to avoid the strong disorder in the outmost…

Theory for the Charge-Density-Wave Mechanism of 3D Quantum Hall Effect.
TLDR
A theory for the CDW mechanism of 3D quantum Hall effect is developed and a rare case, in which a magnetic field can induce an order-parameter phase Transition in one direction but a topological phase transition in other two directions, both depend on one magnetic field is explored.

TLDR
The observation of an unconventional Hall response in the quantum limit of the bulk semimetal HfTe5, adjacent to the three-dimensional quantum Hall effect of a single electron band at low magnetic fields is reported.
Three-dimensional quantum Hall effect and metal–insulator transition in ZrTe5
TLDR
Evidence of the three-dimensional quantum Hall effect and a magnetic-field-driven quantum phase transition are observed in zirconium pentatelluride crystals, providing experimental evidence of the 3D QHE and a promising platform for further exploration of exotic quantum phases and transitions in 3D systems.

Quantum Hall effect in a bulk antiferromagnet EuMnBi2 with magnetically confined two-dimensional Dirac fermions
TLDR
A bulk half-integer quantum Hall effect in a layered antiferromagnet EuMnBi2, in which field-controllable Eu magnetic order significantly suppresses the interlayer coupling between the Bi layers with Dirac fermions, will pave a route to the engineering of magnetically functionalized Dirac materials.
