  text: 'Lead halide perovskites enjoy a number of remarkable optoelectronic properties.
    To explain their origin, it is necessary to study how electromagnetic fields interact
    with these systems. We address this problem here by studying two classical quantities:
    Faraday rotation and the complex refractive index in a paradigmatic perovskite
    CH3NH3PbBr3 in a broad wavelength range. We find that the minimal coupling of
    electromagnetic fields to the k⋅p Hamiltonian is insufficient to describe the
    observed data even on the qualitative level. To amend this, we demonstrate that
    there exists a relevant atomic-level coupling between electromagnetic fields and
    the spin degree of freedom. This spin-electric coupling allows for quantitative
    description of a number of previous as well as present experimental data. In particular,
    we use it here to show that the Faraday effect in lead halide perovskites is dominated
    by the Zeeman splitting of the energy levels and has a substantial beyond-Becquerel
    contribution. Finally, we present general symmetry-based phenomenological arguments
    that in the low-energy limit our effective model includes all basis coupling terms
    to the electromagnetic field in the linear order.'

  text: 'We use general symmetry-based arguments to construct an effective model suitable
    for studying optical properties of lead halide perovskites. To build the model,
    we identify an atomic-level interaction between electromagnetic fields and the
    spin degree of freedom that should be added to a minimally coupled k⋅p Hamiltonian.
    As a first application, we study two basic optical characteristics of the material:
    the Verdet constant and the refractive index. Beyond these linear characteristics
    of the material, the model is suitable for calculating nonlinear effects such
    as the third-order optical susceptibility. Analysis of this quantity shows that
    the geometrical properties of the spin-electric term imply isotropic optical response
    of the system, and that optical anisotropy of lead halide perovskites is a manifestation
    of hopping of charge carriers. To illustrate this, we discuss third-harmonic generation.'
