On the universality of thermodynamics and $\eta/s$ ratio for the charged Lovelock black branes

Understand

We investigate general features of charged Lovelock black branes by giving a detailed description of geometrical, thermodynamic and holographic properties of charged Gauss-Bonnet (GB) black branes in five dimensions.

• We show that when expressed in terms of effective physical parameters, the thermodynamic behaviour of charged GB black branes is completely indistinguishable from that of charged Einstein black branes.
• Moreover, the extremal, near-horizon limit of the two classes of branes is exactly the same as they allow for the same AdS$_2\times R_3$, near-horizon, exact solution.
• This implies that, although in the UV the associated dual QFTs are different, they flow in the IR to the same fixed point.
