Rotational holographic transport from Kerr-Newman-AdS black hole

We consider rotational holographic transport in strongly coupled 2+1-dimensional systems, from the point of view of 3+1-dimensional gravity. We consider the moment of inertia I as a kind of transport coefficient, identified with the moment of inertia of a charged rotating black hole in AdS4 background. In the low-temperature region, we find the behavior of the density I/A with temperature T and angular velocity ω and find a quadratic behavior for ∂(I/A)/∂ω with T, in the presence of some charge Q.
