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:

Spin dynamics of complex oxides, bismuth-antimony alloys, and bismuth chalcogenides
TL;DR: In this article, the spin-orbit interaction and spin lifetimes for complex oxides and bismuth-antimony alloys were derived from the Kubo formula and using Berry curvatures evaluated from a tight-binding Hamiltonian, which applies to all nonmagnetic materials.

Many-body Effects in Graphene
TL;DR: Tse et al. as mentioned in this paper studied the many-body effects in graphene due to Coulomb interaction and electron-phonon interaction and formulated the theory for Coulomb drag in double-layer graphene, finding zero drag if one of the graphene layers is intrinsic and a non-zero drag exhibiting a similar behavior to regular bilayer drag if both graphene layers are extrinsic.

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.
