We show how the coupling between opposite edge states, which overlap in a constriction
made of the topological insulator mercury telluride (HgTe), can be employed both for …

The exotic topological surface states of Dirac or Weyl semimetals, namely Fermi arcs, are
predicted to be spin polarized, while their spin polarization nature is still not revealed by …

We investigate electron interferometry of edge states in topological insulators. We show that
when interboundary coupling is induced at two quantum point contacts of a four terminal …

We propose an intrinsic three-dimensional Fabry-Pérot type interferometer, coined “higher-
order interferometer,” that is based on the chiral hinge states of second-order topological …

We investigate transport in the network of valley Hall states that emerges in minimally
twisted bilayer graphene under interlayer bias. To this aim, we construct a scattering theory …

A topological pn junction (TPNJ) is an important concept to control spin and charge transport
on a surface of three-dimensional topological insulators (3D-TIs). Here we report successful …

We study the tunneling through a two-dimensional topological insulator with topologically
protected edge states. It is shown that the tunneling probability can be quantized in a broad …

Recently, it has been shown that multiterminal superconducting nanostructures may
possess topological properties that involve Berry curvatures in the parametric space of the …

We analyze theoretically the bound-state spectrum of an Aharonov Bohm ring in a two-
dimensional topological insulator using the four-band model of HgTe quantum wells as a …

We present a detailed study of the electronic and spin-orbit properties of single and bilayer
graphene in proximity to the topological insulator Bi 2 Se 3. Our approach is based on first …
