The IM-cut Polyakov loop on the periodic lattice of |$6^3 \times 4$| at |$\beta = 6.0$| in the deconfined phase. The cut region of the Dirac mode is (a) |$|\lambda | \in (0.5a^{-1},1.0a^{-1})$|⁠, (b) |$|\lambda | \in (1.0a^{-1},1.5a^{-1})$|⁠, and (c) |$|\lambda | \in (1.5a^{-1},2.0a^{-1})$|⁠, respectively.
