Abstract
We report the observation of a mode associated with a topological defect in the bulk of a 2D photonic material by introducing a vortex distortion to a hexagonal lattice analogous to graphene. The observed modes lie midgap at zero energy and are closely related to Majorana bound states in superconducting vortices. This is the first experimental demonstration of the Jackiw-Rossi model [R. Jackiw and P. Rossi, Nucl. Phys. B190, 681 (1981)NUPBBO0550-321310.1016/0550-3213(81)90044-4].
