Fig. 2: Acceleration performance of SUAD topological pumping.

a(i) Pseudospin dynamics of edge modes \(\left|{{{\mathcal{L}}}}\right\rangle\) and \(\left|{{{\mathcal{R}}}}\right\rangle\) on Bloch spheres for three pumping schemes with L = 40 and 60 mm; (ii) Occupation probabilities of \(\left|{{{\mathcal{R}}}}\right\rangle\) along the system evolution with L = 40 and 60 mm. b(i) Theoretically calculated light propagation; (ii) Experimentally captured intensities at the output facet; (iii) Experimental light intensity profiles of the samples with L = 40 mm for the three pumping schemes. c Counterpart of b for L = 60 mm. Data in a, b(i) and c(i) are obtained by solving CME with the full Hamiltonian \({\widehat{H}}(z)\).
