Giant anomalous Josephson effect as a probe of spin texture in topological insulators

Niklas Hüttner, Andreas Costa, Leandro Tosi +9

Surface states of topological insulators feature chiral spin-momentum locking. When such states are used as weak link between two superconductors, their spin texture gives rise to…

Magnetic field-bias current interplay in HgTe-based three-terminal Josephson junctions

J. Thieme, W. Himmler, F. Dominguez +8

We investigate HgTe/Nb-based three-terminal Josephson junctions in T-shaped and X-shaped geometries and their critical current contours (CCCs). By decomposing the CCCs into the con…

Quantum Hall effect and current distribution in the 3D topological insulator HgTe

S. Hartl, L. Freund, M. Kühn +8

We study the quantum Hall effect (QHE) in the three-dimensional topological insulator HgTe, which features topological Dirac-type surface states in a bulk gap opened by strain. Des…

Anomalous conductance steps in three-dimensional topological insulator HgTe-based quantum point contacts

Elisabeth Richter, Michael Barth, Dmitriy A. Kozlov +8

We explore electrical transport through a point contact in strained HgTe, a three-dimensional topological insulator. In the absence of a magnetic field , there is no quantizatio…

Supercurrent interference in HgTe Josephson junctions

Wolfgang Himmler, Ralf Fischer, Michael Barth +8

Wires made of topological insulators (TI) are a promising platform for searching for Majorana bound states. These states can be probed by analyzing the fractional ac Josephson effe…

-periodic supercurrent tuned by an axial magnetic flux in topological insulator nanowires

Ralf Fischer, Jordi Picó-Cortés, Wolfgang Himmler +7

Topological insulator (TI) nanowires in proximity with conventional superconductors have been proposed as a tunable platform to realize topological superconductivity and Majorana z…
