Counterpropagating topological and quantum Hall edge channels
Saquib Shamim, Pragya Shekhar, Wouter Beugeling +7
The survival of the quantum spin Hall edge channels in presence of an external magnetic field has been a subject of experimental and theoretical research. The inversion of Landau l…

Emergent quantum Hall effects below mT in a two-dimensional topological insulator
Saquib Shamim, Wouter Beugeling, Jan Böttcher +7
The realization of the quantum spin Hall effect in HgTe quantum wells has led to the development of topological materials which, in combination with magnetism and superconductivity…

Interacting topological edge channels
Jonas Strunz, Jonas Wiedenmann, Christoph Fleckenstein +10
Electrical currents in a quantum spin Hall insulator are confined to the boundary of the system. The charge carriers can be described as massless relativistic particles, whose spin…
