Impurity as a probe of Berry curvature and wavefunction winding in gapped two-band models
Reda Nabil, Pascal Simon, Andrej Mesaros
We explore the possibility of using quasiparticle interference near impurities to extract non-local properties of bands. Focusing on the minimal two-band description of a system wi…
Chiral chains with two valleys and disorder of finite correlation length
Jean-Baptiste Touchais, Pascal Simon, Andrej Mesaros
In one-dimensional disordered systems with a chiral symmetry it is well-known that electrons at energy avoid localization and simultaneously exhibit a diverging density of…
Robust propagating in-gap modes due to spin-orbit domain walls in graphene
Jean-Baptiste Touchais, Pascal Simon, Andrej Mesaros
Recently, great experimental efforts towards designing topological electronic states have been invested in layered incommensurate heterostructures which form various nano- and meso…
Interplay between electronic topology and crystal symmetry: Dislocation-line modes in topological band-insulators
Robert-Jan Slager, Andrej Mesaros, Vladimir Juricic +1
We elucidate the general rule governing the response of dislocation lines in three-dimensional topological band insulators. According to this ${\bf K}\text{-}{\bf b}\text{-}{\bf t}…
The space group classification of topological band insulators
Robert-Jan Slager, Andrej Mesaros, Vladimir Juricic +1
Topological band insulators (TBIs) are bulk insulating materials which feature topologically protected metallic states on their boundary. The existing classification departs from t…
Zero-energy states bound to a magnetic pi-flux vortex in a two-dimensional topological insulator
Andrej Mesaros, Robert-Jan Slager, Jan Zaanen +1
We show that the existence of a pair of zero-energy modes bound to a vortex carrying a pi-flux is a generic feature of the topologically non-trivial phase of the M-B model, which w…
