Topological edge states.
(a) Band dispersion of a ribbon system of 36 hexagons with t1 = 1.1t0 cladded from both sides by 10 hexagons with t1 = 0.9t0. (b) Real-space distribution of the in-gap states associated with the red solid dispersion curves in (a). (c,d) Real-space distributions of current densities in pseudospin-up and -down channels at the momenta indicated by the red and green dots 1 and 2 in (a) within the rhombic area sketched by dashed line in (b); the excess currents in pseudospin-up and -down channels are indicated by red and green arrows in (b).
