夸克-胶子等离子体的磁分量

Magnetic Component of Quark-Gluon Plasma

Jinfeng Liao, Edward Shuryak

摘要:

我们描述了sQGP的“磁场景”的最新发展。我们表明,在$T=(0.8-1.3)T_c$有一个稠密的等离子体的单极子,能够支持亚稳态通量管。它们的存在允许定量地解释在晶格上计算的静态$\bar Q Q$势能的非平凡$T$依赖性。通过分子动力学模拟,我们得到了输运性质(剪切粘度和扩散常数),并表明最好的液体是由最对称的等离子体,具有50%-50%的电和磁电荷。结果接近于RHIC观测到的“理想液体”。

英文摘要:

We describe recent developments of the "magnetic scenario" of sQGP. We show that at $T=(0.8-1.3)T_c$ there is a dense plasma of monopoles, capable of supporting metastable flux tubes. Their existence allows to quantitatively explained the non-trivial $T$-dependence of the static $\bar Q Q$ potential energy calculated on the lattice. By molecular dynamics simulation we derived transport properties (shear viscosity and diffusion constant) and showed that the best liquid is given by most symmetric plasma, with 50%-50% of electric and magnetic charges. The results are close to those of the ``perfect liquid'' observed at RHIC.
