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:

Realization of Dirac Cones in Few Bilayer Sb(111) Films by Surface Modification
Hui Pan,Xuesen Wang +1 more
TL;DR: It is shown that an ideal Dirac cone with linear dispersion of topological surface states near the zone center can be realized by functionalizing both surfaces of the film with oxygen, which enhances spin-orbital coupling.

Dirac Hierarchy in Acoustic Topological Insulators.
Li-Yang Zheng,Johan Christensen +1 more
TL;DR: In this paper, an acoustic 3D honeycomb lattice that features a Dirac hierarchy comprising an eightfold bulk Dirac cone, a 2D fourfold surface state, and a 1D twofold hinge state Dirac cones is presented, where the lifting of the Dirac degeneracy in each hierarchy allows the 3D lattice to appear as a first-order topological insulator with 2D topological surface states, a second-order TI exhibiting 1D hinge states, and an 0D midgap corner states.

Quantum spin Hall effect in graphene
Charles L. Kane,Eugene J. Mele +1 more
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.
