WebAbstract We demonstrate all robust bound states in the continuum in photonic crystal slabs are vortex centers in the polarization directions of far-field radiation. They are robust because they carry quantized topological charges, which are conserved if the system is invariant under parity-time ( PT) and up-down mirror flip operations. • Hsu C., Zhen B., Stone A.D., Joannopoulos J.D., Soljačić M.
