(a) Pumped current Iσ as a function of the Fermi energy EF. (b) Pumped current as a function of energy with different disorders. The Chern number of the Rashba wire is plotted in the inset of panel (b) with an increase of the disorder w. Here N = 3, NT = 500N, and the results are averaged over 400 sample configurations.
