Unconventional Fermi surface in an insulating state
Insulators occur in more than one guise; a recent finding was a class of topological
insulators, which host a conducting surface juxtaposed with an insulating bulk. Here, we …

Surface electronic structure of the topological Kondo-insulator candidate correlated electron system SmB6
Abstract The Kondo insulator SmB6 has long been known to exhibit low-temperature
transport anomalies whose origin is of great interest. Here we uniquely access the surface …

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 …
