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…
Hearing the shape of a Dirac drum: Dual quantum Hall states on curved surfaces
Ioachim Dusa, Denis Kochan, Maximilian Fürst +2
The geometry of a physical system is intimately related to its spectral properties, a concept colloquially referred to as "hearing the shape of a drum". Three-dimensional topologic…
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…
Topological insulator constrictions -- Dirac particles in a magneto-chiral box
Michael Barth, Maximilian Fürst, Raphael Kozlovsky +2
We study magneto-transport through topological insulator nanowires shaped in the form of a constriction, as can be obtained by etching techniques. The magnetic field is coaxial, po…
