Conductances of the topological phase.
(a) Schematic configuration of a six-terminal Hall bar where a topological sample (light blue region) with t1 = 1.1t0 is embedded in a trivial environment (gray region) with t1 = 0.9t0. The size of topological scattering region is 240a0 × 120a0 and the width of each semi-infinite lead is 40a0. The injected current flows along the edges of topological sample as indicated by the red parts between electrodes. (b) Longitudinal and Hall conductances of the Hall bar as a function of energy of incident electrons. The on-site energy is taken ε0 = 0. A rhombic topological sample is taken for ease of calculation.
