○ Abstract: In this work, we propose a photonic analog of the moire superlattice based on dielectric resonator
quasi-atoms. In sharp contrast to van der Waals materials with weak interlayer coupling, we
firstly realize the strong coupling regime in a moire superlattice, characterized by cascades of
robust topological flat bands at large twist angles. Finally, we identify a new type of waveguide
phenomena characterized by SU(2) Wess-Zumino terms, featuring an interesting analogy
between classical photonics and fundamental quantum field theory.
