Simulations of An Edge Wavepacket Propagating in a Fractal Lattice

Caption

a-e Evolution of topological edge states in the fractal SG(4) lattice. a Intensity distribution of the initial field constructed from a truncated topological edge state in the fractal lattice. b-e Intensity distribution at propagation distances . f-j Evolution in the fractal lattice containing on-site disorder of , whose position is marked by the blue dot. The wavepacket displays topologically-protected edge transport around the corners and is unaffected by the disorder. The color bar indicates the field intensity.
