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 Hall Effect and Nonlocal Transport in SmB6: Evidence for Surface Conduction
A topological insulator (TI) is an unusual quantum state in which the insulating bulk is
topologically distinct from vacuum, resulting in a unique metallic surface that is robust …

Fermi surface in the absence of a Fermi liquid in the Kondo insulator SmB6
The search for a Fermi surface in the absence of a conventional Fermi liquid has thus far
yielded very few potential candidates. Among promising materials are spin-frustrated Mott …
