The quantum Hall effect (QHE) is traditionally considered to be a purely two-dimensional (2D) phenomenon. Recently, however, a three-dimensional (3D) version of the QHE was reported in the Dirac semimetal ZrTe 5 . It was proposed to arise from a magnetic-field-driven Fermi surface instability, transforming the original 3D electron system into a stack of 2D sheets. Here, we report thermodynamic, spectroscopic, thermoelectric and charge transport measurements on such ZrTe 5 samples. The measured… Expand

Observation of quantum topological Hall effect in the Weyl semimetal candidate HgSe.
A broad plateau was discovered in the ordinary Hall resistance in the quantum limit and a well-developed plateau-like behaviour in a phenomenologically-introduced "longitudinal" Hall resistivity was detected, which is identified with the discovery of half-integer quantum spin Hall effect in HgSe.

This paper discovers the pressure-induced 3D Dirac semimetal to superconductor transition in ZrTe5 and indicates the observed two-stage superconducting behavior is correlated to the structural phase transition from ambient Cmcm phase to high-pressure C2/m phase around 6 GPa, and to a mixture of two high- pressure phases of C 2/m and P-1 above 20 GPa.

Magnetoinfrared Spectroscopy of Landau Levels and Zeeman Splitting of Three-Dimensional Massless Dirac Fermions in ZrTe(5).
The splitting of the Landau levels provides direct, bulk spectroscopic evidence that a relatively weak magnetic field can produce a sizable Zeeman effect on the 3D Dirac fermions, which lifts the spin degeneracy of Landau Levels. Expand
