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.

Topological insulators, topological superconductors and Weyl fermion semimetals: discoveries, perspectives and outlooks

TL;DR: Theoretically, topological physics in lower dimensional condensed matter systems is an experimental reality since the bulk-boundary correspondence can be probed experimentally in lower dimensions as mentioned in this paper.

Ultrathin Topological Insulator Bi2Se3 Nanoribbons Exfoliated by Atomic Force Microscopy

TL;DR: This paper reports the first controlled mechanical exfoliation of Bi(2)Se(3) nanoribbons (>50 QLs) by an atomic force microscope (AFM) tip down to a single QL, which afford interesting candidates for studying the transition from quantum spin Hall surface to edge states.

Magnetic Proximity Effect as a Pathway to Spintronic Applications of Topological Insulators

TL;DR: In this article, the long range ferromagnetic at ambient temperature can be induced in Bi2-xMnxTe3 by the magnetic proximity effect through deposited Fe overlayer, which opens a new path to interface-controlled ferromagnetism in TI-based spintronic devices.

Chiral anomaly, charge density waves, and axion strings from Weyl semimetals

TL;DR: In this paper, the axion string can be realized as the (screw or edge) dislocations in the charge density wave, which provides a simple physical picture for the elusive axion strings, which have important implications for dissipationless transport properties of Weyl semimetals with broken symmetry.

A large-energy-gap oxide topological insulator based on the superconductor BaBiO3

TL;DR: In this article, it was shown that a known oxide superconductor, BaBiO3, can be doped into a topological insulating state, which would simplify topologically insulator-superconductor structures.

Quantum spin Hall effect in graphene

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.
