Query: Thermodynamic geometry and phase transition of spinning AdS black holes   Employing the thermodynamic geometry approach, we explore phase transition of
four dimensional spinning black holes in an anti-de Sitter (AdS) spaces and
found the following novel results. (i) Contrary to the charged AdS black hole,
thermodynamic curvature of the spinning AdS black hole diverges at the critical
point, without needing normalization.(ii) There is a certain region with small
entropy in the space of parameters for which the thermodynamic curvature is
positive and the repulsive interaction dominates. Such behavior exists even
when the pressure is extremely large. (iii) The dominant interactions in the
microstructure of extremal spinning AdS black holes are strongly repulsive,
which is similar to an ideal gas of fermions at zero temperature. (iv) The
maximum of thermodynamic curvature, $ \left\vert R\right\vert $, is equal to
$C_{{}_{P}}$ maximum values for the Van der Waals fluid in the supercritical
region. While for the black hole, they are close to each other near the
critical point.
