Excitation dynamics in a photon fluid with both local and nonlocal interactions are investigated theoretically. Collective excitations are found to display a gapped Bogoliubov spectrum, which at low energies corresponds to that of massive phonons with a relativistic energy-momentum relation. This could provide a setting for analog simulations of semiclassical gravity and quantum gravity phenomenology.
