      abstract     = {Many-body interactions in topological quantum systems can
                      give rise to new phases of matter, which simultaneously
                      exhibit both rich spatial features and topological
                      properties. In this work, we consider spinless fermions on a
                      checkerboard lattice with nearest and next-to-nearest
                      neighbor interactions. We calculate the phase diagram at
                      half filling, which presents, in particular, an
                      interaction-induced quantum anomalous Hall phase. We study
                      the system at incommensurate fillings using an unrestricted
                      Hartree-Fock ansatz and report a rich zoo of solutions such
                      as self-trapped polarons and domain walls above an
                      interaction-induced topological insulator. We find that, as
                      a consequence of the interplay between the
                      interaction-induced topology and topological defects, these
                      domain walls separate two phases with opposite topological
                      invariants and host topologically protected chiral edge
                      states. Finally, we discuss experimental prospects to
                      observe these novel phenomena in a quantum simulator based
                      on laser-dressed Rydberg atoms in an optical lattice.},
