In so-called topological Anderson insulators, it has been predicted 4 that the emergence of protected edge states and quantized transport can be induced, rather than inhibited, by the addition of sufficient disorder to a ... WebApr 6, 2024 · Recently, a new family of symmetry-protected higher-order topological insulators has been proposed and was shown to host lower-dimensional boundary states. However, with the existence of the strong disorder in the bulk, the crystal symmetry is broken, and the associated corner states are disappeared. It is well known that the …

WebApr 21, 2024 · Photonic Topological Anderson Insulators. The hallmark property of two-dimensional topological materials is the incredible robustness of the quantized Hall conductivity to disorder. That robustness arises from the fact that in the topological band gap, transport can occur only along the edges modes, which are immune to scattering. In our waveguide structures, we use a helix pitch of Z = 1 cm, a radius of R = 10 μm and a nearest-neighbour spacing of a = 14 μm; at our probe wavelength (λ = 633 nm), this corresponds to a dimensionless gauge field strength of A = kRΩa = 1.26, with k = 2πn0/λ, Ω = 2π/Z, an ambient refractive index n0 = 1.45 and a = … See more We extract the decay length of the edge state from the experimental data. To achieve this, we analyse the intensity profile of the light propagating along the edge.
