SmB6: A Promising Candidate for a Topological Insulator
Abstract
Three-dimensional topological insulators represent a new quantum state. They were originally proposed by a theoretical approach, but subsequently observed experimentally, e.g., in Bi 1- x Sb x and Bi 2- x Y x X 3 with X=Se and Y=Ca as well as X=Te and Y=Sn. A characteristic feature is the existence of metallic surface states with an odd number of Dirac points, which are protected by the time reversal symmetry. Furthermore, it was also suggested that some of the so-called Kondo insulators might be topological insulators. Here, we predict on the basis of calculations of topological indices and of spectrum of surface states of a detailed model, that SmB 6 should indeed be a strong topological insulator. We suggest that the metallic surface states of this strong topological insulator are hitherto unexplained in-gap states. Note that, to distiguish it from the systems mentioned above, SmB 6 is a stoichiometric compound.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
