Strong coupling with circularly polarized vacuum fluctuations offers a viable route to
manipulate molecular chirality. While experiments are advancing toward the realization of
chiral cavities, a mean-field theoretical framework for describing electron–photon interaction
in this platform has been missing. Here, we present a mean-field theory that can be
systematically improved to capture the chiral correlation effects responsible for the
enantioselective power of chiral light. We use strong coupling Møller–Plesset perturbation …
