      abstract     = {Understanding the robustness of topological phases of
                      matter in the presence of interactions poses a difficult
                      challenge in modern condensed matter, showing interesting
                      connections to high-energy physics. In this work, we
                      leverage these connections to present a complete analysis of
                      the continuum long-wavelength description of a generic class
                      of correlated topological insulators: Wilson-Hubbard
                      topological matter. We show that a Wilsonian renormalization
                      group (RG) approach, combined with the so-called topological
                      Hamiltonian, provide a quantitative route to understand
                      interaction-induced topological phase transitions that occur
                      in Wilson-Hubbard matter. We benchmark two-loop RG
                      predictions for a quasi-1D Wilson-Hubbard model by means of
                      exhaustive numerical simulations based on matrix product
                      states (MPS). The agreement of the RG predictions with MPS
                      simulations motivates the extension of the RG calculations
                      to higher-dimensional topological insulators.},
