Lead halide perovskites enjoy a number of remarkable optoelectronic properties that interest both ‘blue skies researchers’ and applied scientists. While the former are trying to understand what makes this material special, the latter are working towards novel technologies, such as solar cells. In this talk, I will present a collaborative theoretical/experimental study that argued that the interaction of lead halide perovskites with electromagnetic fields is ‘special’ due to high polarizability of its constituents. To this end, we used symmetry considerations to introduce a phenomenological model Hamiltonian, and then benchmarked it against a measured angle of rotation in the Faraday effect.
