(color online) (a) Sx (blue) and Sp (green) versus eigenenergy Eβ, respectively. (b) versus Eβ. (c) A partial enlarged view of panel (b) for eigenstates with Eβ near . The vertical dashed line (cyan) denotes and the horizontal dashed ones (black) denote . Here, λ = −0.9, α = −0.52, and the lattice size N = 1597, 4181, and 6765, respectively.
