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…
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…
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…
Tracing Dirac points of topological surface states by ferromagnetic resonance
Laura Pietanesi, Magdalena Marganska, Thomas Mayer +13
Ferromagnetic resonance is used to reveal features of the buried electronic band structure at interfaces between ferromagnetic metals and topological insulators. By monitoring the…
Electron quantum optics in graphene
Himadri Chakraborti, Cosimo Gorini, Angelika Knothe +9
In the last decade, graphene has become an exciting platform for electron optical experiments, in many aspects superior to conventional two-dimensional electron gases (2DEGs). A ma…
