The cover illustrates the pseudospinmediated vortex generation in the super‐honeycomb lattice. The lattice band structure in the left‐bottom corner displays a flat band, pseudospin‐1/2 and pseudospin‐1 Dirac cones. If the modes of the Dirac cones corresponding to one sublattice are excited, as highlighted by the flickers in the band structure, the beam will undergo conical diffraction and generate the vortex (the color of the ring represents the phase) during propagation.
