Abstract

In this work, we examine the Kerr/CFT correspondence for magnetized black holes arising from Kaluza--Klein theory, demonstrating that Kerr/CFT holography persists beyond the traditional Einstein--Maxwell framework. Notably, unlike in the Einstein--Maxwell case, the massless neutral scalar field equation here is fully separable into radial and angular parts. This separability reveals a hidden conformal symmetry in the near--horizon, low--frequency regime, providing further support for the robustness of Kerr/CFT dualities in extended gravitational theories.
