Weyl points are band-crossing singularities in 3D crystals that host Weyl fermions, leading to Weyl semimetals with topologically protected chiral surface states and high electron mobility. Photonic analogues, found in chiral crystals and metamaterials, exhibit photonic Weyl points with robust surface modes and unusual scattering properties.
Coupling quantum electronic states to cavity photons has given rise to polaritonics, and its topological extension is rapidly advancing. Yet, strong coupling between topological electronic systems and nontrivial chiral photonic edge modes near optical Weyl points remains largely unexplored. This internship will develop a Hamiltonian model that can be solved analytically and use numerical simulations (finite element and FDTD) to assess experimental platforms capable of realizing such light–matter interactions.
