Fig. 3: Influence of disorders on the reentrant topological transition.
From: Reentrant topological phases and spin density wave induced by 1D moiré potentials
Disorder averaged real-space winding number \(\overline{\nu }\) and energy gap \(\overline{\Delta E}\) are plotted as functions of mo under the OBC. Disorder is added on the spin-dependent hopping tj = t + Wj (a), spin-flip hopping tsj = ts + Wj (b), Zeeman potential mzj = mz + Wj (c), and all these three components (d). Other parameters are the same as Fig. 1(c), Wj ∈ [ − W, W] with W = 0.2, and 20 different disorder realizations are used. Error bars indicate the standard deviation of the sampled data between different disorder realizations.
