  text: We present a minimal model of ferroelectric large polarons, which are suggested
    as one of the mechanisms responsible for the unique charge transport properties
    of hybrid perovskites. We demonstrate that short-ranged charge–rotor interactions
    lead to long-range ferroelectric ordering of rotors, which strongly affects the
    carrier mobility. In the nonperturbative regime, where our theory cannot be reduced
    to any of the earlier models, we reveal that the polaron is characterized by large
    coherence length and a roughly tenfold increase of the effective mass as compared
    to the bare mass. These results are in good agreement with other theoretical predictions
    for ferroelectric polarons. Our model establishes a general phenomenological framework
    for ferroelectric polarons providing the starting point for future studies of
    their role in the transport properties of hybrid organic-inorganic perovskites.
