Generalised Planar Black Holes and the Holography of Hydrodynamic Shear

Understand

AdS black holes with planar event horizon topology play a central role in AdS/CFT holography, and particularly in its applications.

• Generalisations of the known planar black holes can be found by considering the Plebanski--Demianski metrics, a very general family of exactly specified solutions of the Einstein equations.
• These generalised planar black holes may be useful in applications.
• We give a concrete example of this in the context of the holographic description of the Quark-Gluon Plasma (QGP).
