流体/重力对应:紧化D4-branes中的二阶输运系数

Fluid/gravity correspondence: Second order transport coefficients in compactified D4-branes

Chao Wu, Yidian Chen, Mei Huang

摘要:

我们发展的边界导数展开(BDE)形式主义的流体/重力对应的非共形版本通过紧化,近极值黑D4-膜。我们提供了9个二阶输运系数的显式计算,即,强耦合、不带电、非共形的相对论流体的$τ_π,~τ_π^*,~τ_Π,~λ_{1,2,3}$和$ξ_{1,2,3}$是紧化的、近极值黑D4-膜的全息对偶。我们还表明,在这项工作中考虑的非共形流体是免费的因果问题,并承认Haack-Yarom关系$4λ_1+λ_2=2ητ_π$。

英文摘要:

We develop the boundary derivative expansion (BDE) formalism of fluid/gravity correspondence to nonconformal version through the compactified, near-extremal black D4-brane. We offer an explicit calculation of 9 second order transport coefficients, i.e., the $τ_π,~τ_π^*,~τ_Π,~λ_{1,2,3}$ and $ξ_{1,2,3}$ for the strongly coupled, uncharged and nonconformal relativistic fluid which is the holographic dual of compactified, near extremal black D4-brane. We also show that the nonconformal fluid considered in this work is free of causal problem and admits the Haack-Yarom relation $4λ_1+λ_2=2ητ_π$.
