高次导数修正对STU模型中$η/s$和电导率的影响

The effect of higher derivative correction on $η/s$ and conductivities in STU model

J. Sadeghi, B. Pourhassan, A. R. Amani

摘要:

本文在STU模型下研究了R荷黑洞的剪切粘滞系数与熵、电导率和热导率的比值。我们将以前的工作推广到具有三种不同电荷的黑洞的情况。实际上,我们用扩散常数来获得剪切粘度与熵的比值。通过应用数值稳定性,我们恢复了以前的结果。此外,我们调查的影响,更高的衍生工具的更正。

英文摘要:

In this paper we study the ratio of shear viscosity to entropy, electrical and thermal conductivities for the R-charged black hole in STU model. We generalize previous works to the case of a black hole with three different charges. Actually we use diffusion constant to obtain ratio of shear viscosity to entropy. By applying the thermodynamical stability we recover previous results. Also we investigate the effect of higher derivative corrections.
