Eling-Oz Formula for Exotic Hairy Black Holes

Understand

We checked Eling-Oz formula [1] for the bulk viscosity of the holographic fluid dual to the exotic black holes [2].

• Initially, Eling and Oz argued that the formula is valid in the high temperature and adiabatic limits.
• In [3] the validity of the formula for $\caln=2^*$ plasma and cascading gauge theory was pushed forward for arbitrary temperatures.
• We successfully verified the formula with the computations of the bulk viscosity [4,5] for a wide range of the temperatures.
