Transport signatures of Van Hove singularities in mesoscopic twisted bilayer graphene
Aleksander Sanjuan Ciepielewski, Jakub Tworzydło, Timo Hyart +1
Magic-angle twisted bilayer graphene exhibits quasi-flat low-energy bands with Van Hove singularities close to the Fermi level. These singularities play an important role in the ex…
Topological states in superlattices of HgTe-class materials for engineering three-dimensional flat bands
Rajibul Islam, Barun Ghosh, Giuseppe Cuono +7
In search of materials with three-dimensional flat band dispersions, using {\em ab-initio} computations, we investigate how topological phases evolve as a function of hydrostatic p…
One-dimensional Dirac electrons on the surface of weak topological insulators
Alexander Lau, Carmine Ortix, Jeroen van den Brink
We show that a class of weak three-dimensional topological insulators feature one-dimensional Dirac electrons on their surfaces. Their hallmark is a line-like energy dispersion alo…
Topological surface states and Andreev bound states in superconducting iron pnictides
Alexander Lau, Carsten Timm
The nontrivial topology of the electronic structure of iron pnictides can lead to the appearance of surface states. We study such states in various strip geometries with a focus on…
