摘要：We investigate the color-Coulomb confinement scenario using a SU(3) lattice gauge simulation.
It is shown that the color-Coulomb heavy-quark potential, defined from the instantaneous part of
the gluon propagator in Coulomb gauge, behaves as a linearly rising potential at large distances,
and the resulting Coulomb string tension is greater than the Wilson-loop string tension. We study
also the behavior of the color-Coulomb instantaneous part in the QGP phase. It is found that the
linearity of the color-Coulomb instantaneous potential remains even at finite temperature.
