a Schematics of the 2D GPCs. b The Brillouin zones. c Band structure of the lattice based on the rhombic primitive unit cell indicated with green dashed lines, the insets plot the eigen electric field distributions of the Dirac point. d Band structure of the lattice based on the hexagonal unit cell, the insets plot the eigen electric field distributions of the double Dirac point. The other parameters are set as μc1 = 0.3 eV, μc2 = 0.6 eV, τ = 1 ps, the lattice constant a = 40 nm
