• Abstract: We implement the equation of motion of the large-N Gross-Neveu model from strong interaction physics in photonic waveguide arrays and study one of its paradigmatic multi-fermion bound state solutions in an optical experiment. The present study constitutes an important first step towards waveguide-based simulations of phenomena relevant for high-energy physics.

  We study theoretically an array of two-level qubits moving relative to a one-dimensional waveguide. When the frequency of this motion approaches twice the qubit resonance frequency, it induces parametric generation of photons and excitation of the qubits. We develop a comprehensive general theoretical framework that incorporates both perturbative diagrammatic techniques and a rigorous master-equation approach.
