Gate tuning from exciton superfluid to quantum anomalous Hall in van der Waals heterobilayer
TL;DR: It is shown that heterobilayers of 2D valley semiconductors can be tuned through interlayer bias between an exciton superfluid, a quantum anomalous Hall insulator, and a QSH insulator.
Theory of topological insulators and its applications
TL;DR: Sengupta et al. as mentioned in this paper examined HgTe and Bi2Te3 as 2D and 3D topological insulators respectively and proposed a new approach which does not distinguish between electrons and holes and efficiently computes the selfconsistent band structure of TIs.

Spin Selectivity of Chiral Mesostructured Iron Oxides with Different Magnetisms.
TL;DR: In this article , the spin selectivity of iron oxides with different magnetisms arising from varying spin alignment was investigated, and it was speculated that the competitive effect between the spin alignment-induced and chirality-induced effective magnetic fields determined the energy splitting of opposite spins in the materials with different magnetic properties.

New Method for High-Accuracy Determination of the Fine-Structure Constant Based on Quantized Hall Resistance
TL;DR: In this article, the Hall voltage of a two-dimensional electron gas, realized with a silicon metal-oxide-semiconductor field effect transistor, was measured and it was shown that the Hall resistance at particular, experimentally well-defined surface carrier concentrations has fixed values which depend only on the fine-structure constant and speed of light, and is insensitive to the geometry of the device.
