(a) The IR-cut Dirac spectral density |$\rho _{\rm IR}(\lambda)\equiv \rho (\lambda)\theta (|\lambda |-\Lambda _{\mathrm {IR}})$|, and (b) the IR-cut Polyakov loop |$\langle L_P\rangle _{\mathrm {IR}}$| on the periodic lattice of |$6^4$| at |$\beta = 5.6$| for the IR-cut of |$\Lambda _{\mathrm {IR}} = 0.5a^{-1}$|.
