## Description

- description: We derive in the present work topological photonic states purely based
    on conventional dielectric material by deforming a honeycomb lattice of cylinders
    into a triangular lattice of cylinder hexagons. The photonic topology is associated
    with a pseudo-time-reversal (TR) symmetry constituted by the TR symmetry supported
    in general by Maxwell equations and the C6 crystal symmetry upon design, which
    renders the Kramers doubling in the present photonic system. It is shown explicitly
    for the transverse magnetic mode that the role of pseudospin is played by the
    angular momentum of the wave function of the out-of-plane electric field. We solve
    Maxwell equations and demonstrate the new photonic topology by revealing pseudospin-resolved
    Berry curvatures of photonic bands and helical edge states characterized by Poynting
    vectors.
