Edge states play a major role in the electron dynamics of topologicalinsulators as they are the only conducting part in such materials. In thiswork, we consider the Haldane model for a 2D topological insulator, subjectedto an intense laser field. We compare the numerically simulated high-harmonicgeneration (HHG) in the bulk of the Haldane model to HHG in correspondingfinite flakes with edge states present, and explain the differences. Inparticular, peaks for energies below the bulk band gap appear in the spectrafor the finite flakes. The positions of these peaks show a strong dependence onthe size of the flakes, which can be explained using the dispersion relationfor the edge states.
