      abstract     = {Reflecting the fundamental interactions of polarized light
                      with magnetic matter, magneto-optical effects are well known
                      since more than a century. The emergence of these phenomena
                      is commonly attributed to the interplay between exchange
                      splitting and spin-orbit coupling in the electronic
                      structure of magnets. Using theoretical arguments, we
                      demonstrate that topological magneto-optical effects can
                      arise in noncoplanar antiferromagnets due to the finite
                      scalar spin chirality, without any reference to exchange
                      splitting or spin-orbit coupling. We propose spectral
                      integrals of certain magneto-optical quantities that uncover
                      the unique topological nature of the discovered effect. We
                      also find that the Kerr and Faraday rotation angles can be
                      quantized in insulating topological antiferromagnets in the
                      low-frequency limit, owing to nontrivial global properties
                      that manifest in quantum topological magneto-optical
                      effects. Although the predicted topological and quantum
                      topological magneto-optical effects are fundamentally
                      distinct from conventional light-matter interactions, they
                      can be measured by readily available experimental
                      techniques.},
