Photonic double Weyl nodal line semimetals achieve independent band translation and rotation as Weyl quasiparticles, creating a distinctive bilateral drumhead surface state.
Theoretical model using an effective Hamiltonian with four degrees of freedom tracks topological charge singularities that merge into a bound state in the continuum ring.
May enable unconventional hyperbolic metamaterial devices by bridging bound states and topological semimetals, supporting dual-mode schemes for optical sensing and switching.
