“…( ) 4 The complete Lagrangian would be the Einstein-Maxwell one. However, the gauge transformation and diffeomorphism of A μ will not contribute to the central term, then we can simply perform in some detail the calculations based on Einstein-Hilbert Lagrangian only.…”

“…Getting the corresponding central charge which is related to the near horizon geometry under consideration is an important step in Kerr/CFT correspondence prescription [1], since this central charge is needed in the dual calculation of entropy using Cardy formula. Subsequently, the Kerr/CFT correspondence [1] was extended to many cases of extremal rotating black holes [3], even to the static charged ones [4].…”

We extend the conjectured Kerr/CFT correspondence to the case of extremal Kerr black holes immersed by an magnetic field, namely the extremal Melvin-Kerr black holes. We compute the central charge which appears in the associated Virasoro algebra generated by a class of diffeomorphisms that satisfies a set of boundary conditions in the near horizon of an extremal Melvin-Kerr black hole. Our results support the Kerr/CFT conjecture, where the macroscopic Bekenstein-Hawking entropy for an extremal Melvin-Kerr black hole matches the result obtained from a dual 2D CFT microscopic computation using Cardy formula. Interestingly, the dual CFT description could be non-unitary, due to the possibility of negative central charge. * haryanto.siahaan@unpar.ac.id
