Confinement in non-Abelian gauge theories is commonly ascribed to percolation of magnetic monopoles, or strings in the vacuum. At the deconfinement phase transition the condensed magnetic degrees of freedom are released into gluon plasma as thermal magnetic monopoles. We point out that within the percolation picture, lattice simulations can be used to estimate the monopole content of the gluon plasma. We show that right above the critical temperature the monopole density remains a constant function of temperature, as in a liquid, and then grows, as in a gas.
非阿贝尔规范理论中的禁闭通常归因于磁单极子或真空中弦的渗流。在去禁闭相变时,凝聚的磁自由度作为热磁单极子释放到胶子等离子体中。我们指出,在渗流图景中,晶格模拟可用于估计胶子等离子体中的磁单极子含量。我们表明,恰好在临界温度之上,磁单极子密度如同在液体中一样保持为温度的常数函数,然后如同在气体中一样增长。
