Query: Temperature Dependence of Linked Gap and Surface State Evolution in the
  Mixed Valent Topological Insulator SmB6   Taken together and viewed holistically, recent theory, low temperature (T)
transport, photoelectron spectroscopy and quantum oscillation experiments have
built a very strong case that the paradigmatic mixed valence insulator SmB6 is
currently unique as a three-dimensional strongly correlated topological
insulator (TI). As such, its many-body T-dependent bulk gap brings an extra
richness to the physics beyond that of the weakly correlated TI materials. How
will the robust, symmetry-protected TI surface states evolve as the gap closes
with increasing T? For SmB6 exploiting this opportunity first requires
resolution of other important gap-related issues, its origin, its magnitude,
its T-dependence and its role in bulk transport. In this paper we report
detailed T-dependent angle resolved photoemission spectroscopy (ARPES)
measurements that answer all these questions in a unified way.
