Transport study of the wormhole effect in three-dimensional topological insulators
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 …
