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 multifermion bound-state solutions in an optical experiment. The present study constitutes an important step towards waveguide-based simulations of phenomena relevant for high-energy physics.
