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…
Topological states in multi-orbital HgTe honeycomb lattices
W. Beugeling, E. Kalesaki, C. Delerue +3
Research on graphene has revealed remarkable phenomena arising in the honeycomb lattice. However, the quantum spin Hall effect predicted at the K point could not be observed in gra…
Dirac Cones, Topological Edge States, and Nontrivial Flat Bands in Two-Dimensional Semiconductors with a Honeycomb Nanogeometry
E. Kalesaki, C. Delerue, C. Morais Smith +3
We study theoretically two-dimensional single-crystalline sheets of semiconductors that form a honeycomb lattice with a period below 10 nm. These systems could combine the usual se…
