TLDR
In topological insulators, spin-orbit coupling and time-reversal symmetry combine to form a novel state of matter predicted to have exotic physical properties as mentioned in this paper, which is called spin−orbit coupling.Abstract:

Topological insulators and thermoelectric materials
TL;DR: Topological insulators (TIs) are a new quantum state of matter which have gapless surface states inside the bulk energy gap as mentioned in this paper, and have been theoretically predicted and experimentally observed.
Journal ArticleDOI
Spin-Orbit Coupled Quantum Gases
TL;DR: In this paper, the experimental and theoretical progresses in studying spin-orbit coupled degenerate atomic gases during the last two years are discussed, and the key message delivered here is that spinorbit coupling can enhance the interaction effects, and make the interaction effect much more dramatic even in the weakly interacting regime.

TL;DR: Graphene is converted from an ideal two-dimensional semimetallic state to a quantum spin Hall insulator and the spin and charge conductances in these edge states are calculated and the effects of temperature, chemical potential, Rashba coupling, disorder, and symmetry breaking fields are discussed.

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.
