In waveguide Quantum Electrodynamics, a few localized atoms send photons into a 1D waveguide. Here we present a platform that switches the roles of light and matter, with state-selective optical-lattice wells acting as quantum emitters radiating ultracold matter waves. This platform has characteristics that complement well other synthetic systems for the study of light-matter interactions. First, the heavier nature of atoms as compared to photons makes the decay dynamics several orders of magnitude slower, with the advantages of enhancing non-Markovian effects and enabling the measurement of the time evolution at the early stages of the decay. Second, the tunability of the system parameters allows for control of the initial states, adiabatic preparation of bound states and readout of the radiation momentum distribution in a time-of-flight picture.
