摘要:

利用SU(2)格点理论的猝灭模拟,研究了中心涡旋下夸克-胶子等离子体中胶子传播子的电磁分量。在朗道规范中,传播子的磁分量在红外区域受到中心涡旋去除的强烈影响,而电分量几乎没有变化。在库仑规范中,包括瞬时相互作用在内的时间-时间耦合子也有来自中心涡旋的重要贡献。其结果是,人们发现,在红外区域的磁自由度强烈耦合到解除禁闭阶段的中心涡。

英文摘要:

We study electric and magnetic components of the gluon propagators in quark-gluon plasma in terms of center vortices by using a quenched simulation of SU(2) lattice theory. In the Landau gauge, the magnetic components of the propagators are strongly affected in the infrared region by removal of the center vortices, while the electric components are almost unchanged by this procedure. In the Coulomb gauge, the time-time correlators, including an instantaneous interaction, also have an essential contribution from the center vortices. As a result, one finds that magnetic degrees of freedom in the infrared region couple strongly to the center vortices in the deconfinement phase.
