Coexistence of pseudospin- and valley-Hall-like edge states in a photonic crystal with C_{3v} symmetry

We demonstrate the coexistence of pseudospin- and valley-Hall-like edge states in a photonic crystal with C_{3v} symmetry, which is composed of three interlacing triangular sublattices with the same lattice constants. By tuning the geometry of the sublattices, three complete photonic band gaps with...
