Kondo insulators combine strong electronic correlations with spin orbit
coupling and thereby provide a potential realization of correlated topological
insulators. We present model calculations which allow us to study the onset of
bulk coherence and concomitant topological edge states from the mixed valence
to local moment regimes. Our real-space dynamical mean-field results include
the detailed temperature dependence of the single particle spectral function on
slab geometries as well as the temperature dependence of the topological
invariant. The relevance of our calculations for candidate materials like SmB6
is discussed.Comment: 7 pages, 6 figure
