Theory for the Charge-Density-Wave Mechanism of 3D Quantum Hall Effect
Theory for the Charge-Density-Wave Mechanism of 3D Quantum Hall Effect
The charge-density-wave (CDW) mechanism of the 3D quantum Hall effect has been observed recently in ZrTe5 [Tang et al., Nature 569, 537 (2019)]. Different from previous cases, the CDW forms on a one-dimensional (1D) band of Landau levels, which strongly depends on the magnetic field. However, its theory is still …
