从规范/引力对偶性看强耦合非共形流体的流体力学

Hydrodynamics of strongly coupled non-conformal fluids from gauge/gravity duality

Todd Springer

摘要:

相对论流体力学的主题是探讨使用规范/重力对偶的工具。本文首先对AdS/CFT和规范/引力对偶作了简要的文献回顾。其次是教学介绍使用这些方法在确定流体动力学色散关系,$w(q)$,在强耦合流体的扰动。剪切和声模扰动在一类特殊的重力场中进行了研究:那些支持度规的物质本质上是标量的。分析解决方案(为了$q^4$和$q^3$分别)的剪切和声模式色散关系的一个子集,这些背景。这里介绍的工作是基于同一作者以前的出版物,虽然也包括一些以前未发表的结果。特别是,在剪切模色散关系的次主导项进行了分析,使用AdS/CFT对应,而没有任何参考的黑洞膜范例。

英文摘要:

The subject of relativistic hydrodynamics is explored using the tools of gauge/gravity duality. A brief literature review of AdS/CFT and gauge/gravity duality is presented first. This is followed by a pedagogical introduction to the use of these methods in determining hydrodynamic dispersion relations, $w(q)$, of perturbations in a strongly coupled fluid. Shear and sound mode perturbations are examined in a special class of gravity duals: those where the matter supporting the metric is scalar in nature. Analytical solutions (to order $q^4$ and $q^3$ respectively) for the shear and sound mode dispersion relations are presented for a subset of these backgrounds. The work presented here is based on previous publications by the same author, though some previously unpublished results are also included. In particular, the subleading term in the shear mode dispersion relation is analyzed using the AdS/CFT correspondence without any reference to the black hole membrane paradigm.
