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

Helicity-dependent photocurrent (HDPC) has been observed in epitaxial thin films of the
three-dimensional topological insulator Sb 2 Te 3 with a thickness of 7, 20, and 30 quintuple …

We investigate the interplay between confinement and the fermion doubling problem in
Dirac-like Hamiltonians. Individually, both features are well known. First, simple electrostatic …

Two-dimensional topological insulators possess two counter propagating edge channels
with opposite spin direction. Recent experimental progress allowed to create ferromagnetic …

We report a metal–insulator like transition in single-crystalline 3D topological insulator Bi 2
Te 3 at a temperature of 230 K in the presence of an external magnetic field applied normal …

A Weyl point in a superconducting nanostructure is a generic minimum model of a
topological singularity at low energies. We connect the nanostructure to normal leads …

Specific features in magnetotransport properties due to gradual forming the topological
