Inside a three-dimensional strong topological insulator, a tube with $h/2e$ magnetic flux carries a pair of protected one-dimensional linear fermionic modes. This phenomenon is known as the ``wormhole effect.'' In this work, we find that the wormhole effect, as a unique degree of freedom, introduces exotic transport phenomena and thus manipulates the transport properties of topological insulators. Our numerical results demonstrate that the transport properties of a double-wormhole system can be… 

Effective curved space-time geometric theory of generic-twist-angle graphene with application to a rotating bilayer configuration

We propose a new kind of geometric e ff ective theory based on curved space-time single valley Dirac theory with spin connection for twisted bilayer graphene under generic twist angle. This model can

Wormhole Effect in a Strong Topological Insulator

An infinitely thin solenoid carrying magnetic flux $\ensuremath{\Phi}$ (a ``Dirac string'') inserted into an ordinary band insulator has no significant effect on the spectrum of electrons. In a

One-dimensional helical transport in topological insulator nanowire interferometers.

The observation of a topologically protected 1D mode of surface electrons in topological insulator nanowires existing at only two values of half magnetic quantum flux due to a spin Berry's phase is reported.

Two-dimensional lattice model for the surface states of topological insulators

The surface states in three-dimensional (3D) topological insulators (TIs) can be described by a two-dimensional (2D) continuous Dirac Hamiltonian. However, there exists the Fermion doubling problem

Ballistic geometric resistance resonances in a single surface of a topological insulator

Transport in topological matter has shown a variety of novel phenomena over the past decade. Although numerous transport studies have been conducted on three-dimensional topological insulators (TIs),

Observation of a large-gap topological-insulator class with a single Dirac cone on the surface

Recent experiments and theories have suggested that strong spin–orbit coupling effects in certain band insulators can give rise to a new phase of quantum matter, the so-called topological insulator,

Colloquium : Topological insulators

Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have protected conducting states on their edge or surface. These states are possible due to

Topological insulators with inversion symmetry

Topological insulators are materials with a bulk excitation gap generated by the spin-orbit interaction that are different from conventional insulators. This distinction is characterized by ${Z}_{2}$

Time- and Site-Resolved Dynamics in a Topological Circuit

The surface states of topological insulators are protected from backscattering, making them a promising resource for computing and materials science. This topological protection is now demonstrated

Lattice model for the surface states of a topological insulator with applications to magnetic and exciton instabilities

A surface of a strong topological insulator (STI) is characterized by an odd number of linearly dispersing gapless electronic surface states. It is well known that such a surface cannot be described

Symmetry-enforced three-dimensional Dirac phononic crystals.

An experimental observation of Dirac points that are enforced completely by the crystal symmetry using a nonsymmorphic three-dimensional phononic crystal is reported, which may release new opportunities for studying elusive (pseudo) and offer a unique prototype platform for acoustic applications.
