(a) The sketch of a four-terminal Hall bar. The blue region is described by the Hamiltonian Eq. (2). The four semi-infinite metallic leads are represented by the orange parts. (b) The Hall conductance as a function of \({m}_{z}/{m}_{0}\) for the clean system. The shallow blue, red, and yellow regions mark the CI, WSM, and normal insulator (NI) phases, respectively. (c) The density plot of Hall conductance in the \({m}_{z}/{m}_{0}\) − \(W/t\) plane for the disordered system. The three black lines (from bottom to top) are plateau-plateau transition lines obtained from the SCBA for \(n=1\), 2, 3 in Eq. (7). The two green lines enclose the CI phase region according to the localization length calculations. (d) The \({{\rm{\Sigma }}}_{z}\) component of the self-energy obtained from the SCBA as a function of \({m}_{z}/{m}_{0}\) and \(W/t\).
