In this paper, the Einstein AdS black brane solution in the presence of a string cloud in the context of d-dimensional massive gravity is introduced. The ratio of shear viscosity to entropy density for this solution violates the KSS bound by applying the Dirichlet boundary and regularity on the horizon conditions. Our result shows that this value is independent of string cloud in any arbitrary dimensions.

存在弦云时体积尺寸对黏度界的影响

本文介绍了 d 维大质量引力背景下弦云存在下的 Einstein AdS 黑膜解。该解决方案的剪切粘度与熵密度之比违反了通过在水平条件上应用狄利克雷边界和规律性的 KSS 约束。我们的结果表明，该值与任意维度的字符串云无关。
