As generalizations of Haldane model, these models support topological insulator and semimetal phases featuring high Chern numbers.

We report on magneto-optical studies of Bi2Se3, a representative member of the 3D topological insulator family.

We theoretically study tunneling of Cooper pairs from a superconductor spanning a two-dimensional topological insulator strip into its helical edge states.

This provides a dynamical mechanism to obtain a topological insulator in the presence of interactions, analogous to the Su-Schrieffer-Heeger model for electrons.

In this regime, our atomic gas corresponds to a phase of matter where Maxwell electrodynamics is replaced by axion electrodynamics: a 3D topological insulator.

The improvement should be attributed to the intrinsic suppressed electron backscattering in a Bi 2 Te 3 topological insulator.

In this work, we probe quantum transport in MnBi 2 Te 4 thin flakes-a topological insulator with intrinsic magnetic order.

We demonstrate the controllable local manipulation of the Dirac surface state in a topological insulator, Bi2Te2Se, which has suppressed bulk carrier density.
