Abstract :  We examine the e ects of correlations on 3D topological insulators
(TIs) as well as topological Weyl semimetals by using cellular dynamical mean- eld theory (CDMFT).
A model relevant to the pyrochlore iridates, a family of complex oxides that might harbour
such phases, is used. We characterize the evolution of the topologically protected surface
states and their disappearance for su ciently strong interactions. We verify the bulk-boundary
correspondence for correlated TIs by computing the quantized magneto-electric response coe cient using the
interacting Green's function. This invariant also identi es a correlated axion insulator between a
TI andWeyl semimetal, a feature absent in a simple mean- eld treatment. We describe consequences for
experiments and for the search for correlated materials with symmetry-protected topological order.
