CFT流体力学:对称性、精确解和引力

CFT Hydrodynamics: Symmetries, Exact Solutions and Gravity

Itzhak Fouxon, Yaron Oz

摘要:

我们考虑有限温度下相对论性共形场论的流体力学及其慢运动极限,在那里它归结为不可压缩的纳维-斯托克斯方程。分析了方程及其解的对称性。我们构造了一维相对论性共形流体动力学运动的有限时间奇点的精确解,并利用它们通过特殊的共形变换生成多维解。然而,这些解决方案,被证明没有非平凡的慢动作限制。构造了一个简单的非平衡定常激波解,并分析了其内部结构。我们证明了共形流体力学的引力对偶描述的推导类似于从玻尔兹曼方程推导流体力学方程。激波解对应于重力作用下的畴壁解。我们证明了非相对论性不可压缩纳维-斯托克斯方程的解在引力整体解的构造中起着特殊的作用。

英文摘要:

We consider the hydrodynamics of relativistic conformal field theories at finite temperature and its slow motions limit, where it reduces to the incompressible Navier-Stokes equations. The symmetries of the equations and their solutions are analyzed. We construct exact solutions with finite time singularities of one-dimensional relativistic conformal hydrodynamic motions, and use them to generate multi-dimensional solutions via special conformal transformations. These solutions, however, are shown to have no non-trivial slow motions limit. A simple non-equilibrium steady state in the form of a shock solution is constructed, and its inner structure is analyzed. We demonstrate that the derivation of the gravitational dual description of conformal hydrodynamics is analogous to the derivation of hydrodynamics equations from the Boltzmann equation. The shock solution is shown to correspond to a domain-wall solution in gravity. We show that the solutions to the non-relativistic incompressible Navier-Stokes equations play a special role in the construction of global solutions to gravity.
