有限全息屏上的混合RG流和流体力学

Mixed RG Flows and Hydrodynamics at Finite Holographic Screen

Yoshinori Matsuo, Sang-Jin Sin, Yang Zhou

摘要:

考虑具有化学势的夸克-胶子等离子体,在规范/引力对偶框架下研究了输运系数的重整化群流。我们首先利用流动方程研究它们,并通过计算任意切片上的格林函数将结果与流体动力学结果进行比较。两个结果完全匹配。通过计算流体力学格林函数,得到了任意尺度下的输运系数。当动量或电荷消失时,输运系数彼此解耦。

英文摘要:

We consider quark-gluon plasma with chemical potential and study renormalization group flows of transport coefficients in the framework of gauge/gravity duality. We first study them using the flow equations and compare the results with hydrodynamic results by calculating the Green functions on the arbitrary slice. Two results match exactly. Transport coefficients at arbitrary scale is ontained by calculating hydrodynamics Green functions. When either momentum or charge vanishes, transport coefficients decouple from each other.
