  SmB6 is one of the candidate compounds for topological Kondo insulators, a
class of materials which combines a non-trivial topological band structure with
strong electronic correlations. Here we employ a multiband tight-binding
description, supplemented by a slave-particle approach to account for strong
interactions, to theoretically study the surface-state signatures in scanning
tunneling spectroscopy (STS) and quasiparticle interference (QPI). We discuss
the spin structure of the three surface Dirac cones of SmB6 and provide
concrete predictions for the energy and momentum dependence of the resulting
QPI signal. Our results also apply to PuB6, a strongly correlated topological
insulator with a very similar electronic structure.
