论文摘要
我们开发了在全息流体的导数扩展中构建主要耗散术语的分析技术。我们的基本成分是经典重力的Crnkovic-witten符合性电流，我们用来提取全息流体的耗散转运系数，假设对热力学的知识和散装黑洞几何的近地平线几何形状的了解。我们将技术应用于非统一的中性流体，以重现剪切粘度的先前结果，并概括了大量粘度的已知表达。
We develop analytic techniques to construct the leading dissipative terms in a derivative expansion of holographic fluids. Our basic ingredient is the Crnkovic-Witten symplectic current of classical gravity which we use to extract the dissipative transport coefficients of holographic fluids, assuming knowledge of the thermodynamics and the near horizon geometries of the bulk black hole geometries. We apply our techniques to non-conformal neutral fluids to reproduce previous results on the shear viscosity and generalise a known expression for the bulk viscosity.
