Figure 2

(a–c) The sign of is plotted on the a - Δ plane, where Sα is the Rényi entropy of the reduced state of subsystem A with size LA = 4, 8, 60 as marked in the graphs. (d–f ) The corresponding plots of majorization M(k) on the k-Δ plane. The red color denotes that (M(k) > 0) and the green color indicates that (M(k) < 0). The parameters are N = 120, δ = 0.3, . In the DMRG calculation, m = 600 states are kept, with the truncation error below 10−12.
