General Hidden Conformal Symmetry of 4D Kerr-Newman and 5D Kerr Black Holes

Understand

There are two known CFT duals, namely the J-picture and the Q-picture, for a four-dimensional Kerr-Newman black hole, corresponding to the angular momentum $J$ and the electric charge $Q$ respectively.

• In our recent study we found a one-parameter class of CFT duals for extremal Kerr-Newman black hole, connecting these two pictures.
• In this paper we study these novel CFT duals for the generic non-extremal Kerr-Newman black hole.
• We investigate the hidden conformal symmetry in the low frequency scattering off Kerr-Newman black hole, from which the dual temperatures could be read.
