强耦合场论的声音:AdS中的准正规模

The Sound of Strongly Coupled Field Theories: Quasinormal Modes In AdS

Karl Landsteiner

摘要:

AdS/CFT对应在过去的几年里已经发展成为研究有限温度和密度下强耦合场论的一个非常有用和强大的工具。特别感兴趣的是近平衡的实时演化,可以通过线性响应理论捕获的政权。通过研究渐近AdS黑洞周围的涨落,AdS/CFT对应允许计算规范不变算子的延迟两点函数。这些全息响应函数的极点起着重要作用:准正规频率。我将回顾这些思想在强耦合夸克-胶子等离子体流体力学和强耦合超流体全息实现中的应用。

英文摘要:

The AdS/CFT correspondence has developed over the last years into a very useful and powerful tool for studying strongly coupled field theories at finite temperature and density. Of particular interest is the regime of near equilibrium real time evolution that can be captured via linear response theory. The AdS/CFT correspondence allows the calculation of retarded two point functions of gauge invariant operators by studying fluctuations around asymptotically AdS black holes. A major role is played by the poles of these holographic response functions: the quasinormal frequencies. I will review the applications of these ideas to the hydrodynamics of the strongly coupled quark gluon plasma and the holographic realization of strongly coupled superfluids.
