Steven S. Gubser, Silviu S. Pufu, Fabio D. Rocha, Amos Yarom

摘要:

我们回顾了规范弦对偶中发展起来的方法来处理强耦合热介质的能量探针的能量损失。在介绍了热介质的黑洞描述之后,我们讨论了重夸克后面的尾弦和它所隐含的拖曳力。然后,我们解释如何解决的线性化爱因斯坦方程的存在下,尾随字符串和提取的解决方案的能量密度和坡印廷矢量的对偶规范理论。我们总结了一些努力,比较这些计算重离子现象学。

英文摘要:

We review methods developed in the gauge-string duality to treat energy loss by energetic probes of a strongly coupled thermal medium. After introducing the black hole description of the thermal medium, we discuss the trailing string behind a heavy quark and the drag force that it implies. We then explain how to solve the linearized Einstein equations in the presence of the trailing string and extract from the solutions the energy density and the Poynting vector of the dual gauge theory. We summarize some efforts to compare these calculations to heavy ion phenomenology.
