摘要：
We study the Coulomb gauge confinement mechanism in the quenched lattice QCD simulations. It is found that the color-Coulomb instantaneous potential in the color-singlet channel between two quarks grows linearly at large distances; namely, the color-Coulomb interaction is a source of color confinement. However, the linearity of this potential remains even in the quark-gluon plasma phase. We discuss the relation between this thermal Coulomb-string tension and a magnetic scaling introduced as an infrared cutoff of the thermal QCD theory.
