Persistence of symmetry-protected Dirac points at the surface of the topological crystalline insulator SnTe upon impurity doping.

We investigate the effect of a non-magnetic donor impurity located at the surface of the SnTe topological crystalline insulator. In particular, the changes on the surface states due to a Sb impurity atom are analyzed by means of simulations of pristine and impurity-doped SnTe. Both semi-infinite and slab geometries are considered within the first-principles approach.

One-Dimensional Moiré Superlattices and Flat Bands in Collapsed Chiral Carbon Nanotubes.

We demonstrate that one-dimensional moiré patterns, analogous to those found in twisted bilayer graphene, can arise in collapsed chiral carbon nanotubes. Resorting to a combination of approaches, namely, molecular dynamics to obtain the relaxed geometries and tight-binding calculations validated against ab initio modeling, we find that magic angle physics occur in collapsed carbon nanotubes. Velocity reduction, flat bands, and localization in AA regions with diminishing moiré angle are revealed, showing a magic angle close to 1°.
