I will present a study of resonant photon-pair interactions in the Fermi gas, using photo-association to ultra-long-range molecules. The cavity transmission spectrum close to these transitions exhibits the anti-crossing characteristic of strong lightmatter coupling, signaling the onset of coherent ‘pair-polaritons’. I will describe the dependence of the optical spectrum on interaction strength, and connect the optical spectrum of the cavity with Tan’s contact, a universal property of the many-body physics of the Fermi gas. This provides a new connection between quantum optics and strongly correlated matter.
