We image the edge states via the third-harmonic generation and demonstrate their robustness against disorder and structural perturbationsWe acknowledge a support from the Air Force Office of Scientific Research (project FA2386-16-1-0002) and the Strategic Fund of the Australian National University.application/pdfen-AU© 2019 The Authors.
