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…
