Visualizing a single wavefront dislocation induced by orbital angular momentum in graphene

Abstract Phase singularities are phase-indeterminate points where wave amplitudes are zero, which manifest as phase vertices or wavefront dislocations. In the realm of optical and electron beams, the phase singularity has been extensively explored, demonstrating a profound connection to orbital angu...
