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.},
