Photons coupled to atomic Rydberg states form Rydberg polaritons that
exhibit properties of both light and strongly-interacting matter. I will describe experiments
characterizing Rydberg polaritons in an optical cavity in which we observe strong
polariton-polariton interactions through antibunching of light. In separate experiments, we show
that degenerate optical cavities with a nonplanar geometry induce effective magnetic fields
for photons, resulting in Landau levels. Combining strongly-interacting Rydberg polaritons with
photonic Landau levels provides a promising route toward realizing Laughlin states of light.
In the second part of my talk, I will describe proposed experiments investigating the
transport properties of strongly interacting atomic Fermi gases. Both Rydberg polaritons and
atomic fermions provide platforms for observing the novel properties of strongly interacting
quantum systems driven out of equilibrium.
