Abstract
We propose the existence, via analytical derivations, novel phenomenologies, and first-principles-based
simulations, of a class of materials that are not only spontaneously optically active, but also for which the
sense of rotation can be switched by an electric field applied to them via an induced transition between the
dextrorotatory and laevorotatory forms. Such systems possess electric vortices that are coupled to a spontaneous
electrical polarization. Furthermore, our atomistic simulations provide a deep microscopic insight into, and
understanding of, this class of naturally optically active materials.
