摘要：We investigate the spectrum of the Faddeev-Popov operator in Coulomb gauge QCD using
quenched SU(3) lattice simulation. In the confinement phase, we observe the accumulation of the
near-zero modes of the FP operator at large lattice volumes, and the color-Coulomb self-energy
diverges in the infrared limit. Moreover, even in the deconfinement phase, the behavior of the FP
eigenvalue density is qualitatively the same as in the confinement phase and the color-Coulomb
self-energy is infrared divergent.
