Abstract
We show that extremal rotating charged black holes have a hidden conformal symmetry. In this regard, we consider the wave equation of a massless scalar field propagating in rotating charged spacetimes and find in the “near region”, the wave equation in extremal limit can be written in terms of SL(2,R) Casimir invariants. Moreover, we obtain the microscopic entropy of the rotating charged black holes and find the correlation function of a near-region scalar field matches to the microscopic greybody factor of the dual 2D CFT.
