Efficient algorithm to compute the Berry conductivity
TL;DR: In this article, a numerical algorithm to calculate the Berry conductivity in topological band insulators is presented. But the method is applicable to cold atom systems as well as solid state setups, both for the insulating case where the Fermi energy lies in the gap between two bulk bands as well in the metallic regime.

Thermoelectric efficiency of topological insulators in a magnetic field
TL;DR: In this paper, the thermoelectric properties of three-dimensional topological insulators in magnetic fields with many holes (or pores) in the bulk were studied, and it was shown that at high density of these holes in the transport direction, ZT can be large due to the contribution of the topologically protected conducting surfaces and the suppressed phonon thermal conductivity.

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.
