A heptagonal defect in the center of a zigzag-edge graphene sheet with 30x16 sites. The spatial distribution of the local density of states of the sites, the local current density of the bonds, and the induced magnetic moment of carbon rings are depicted by blue circles, arrows, and green disks/crosses, respectively.
