Colloquium: Topological band theory
The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

Observation of possible topological in-gap surface states in the Kondo insulator SmB6 by photoemission
SmB6, a well-known Kondo insulator, exhibits a transport anomaly at low temperature. This
anomaly is usually attributed to states within the hybridization gap. Recent theoretical work …

Emergent mystery in the Kondo insulator samarium hexaboride
Samarium hexaboride (SmB6) is an example of a Kondo insulator, in which strong electron
correlations cause a band gap to open. SmB6 hosts both a bulk insulating state and a …
