Query: Quark Spectral Function and Deconfinement at Nonzero Temperature   The maximum entropy method is used to compute the quark spectral function at
nonzero temperature. We solve the gap equation of quantum chromodynamics (QCD)
self-consistently, employing a rainbow kernel which phenomenologically models
results from Dyson-Schwinger equations (DSE) and lattice QCD. We use the
criterion of positivity restoration of the spectral function as a signal for
deconfinement. Our calculation indicates that the critical temperature of
deconfinement $T_d$ is slightly smaller than the one of chiral symmetry
restoration $T_c$: $T_d\sim 94% T_c$ in the chiral limit, and $T_d\sim 96% T_c$
with physical light quark masses. Since these deviations are within the
systematic error of our approach, it is reasonable to conclude that chiral
symmetry restoration and deconfinement coincide at zero chemical potential.
