Abstract: | Motivated by the recent work of the hidden conformal symmetry of the Kerr black hole, we investigate the hidden conformal
symmetry of a Kerr–Sen black hole and a Kerr–Newman–Kasuya black hole. Our result shows the conformal symmetry is spontaneously
broken due to the periodicity of the azimuthal angle. The absorption across section is in consistence with the finite temperature
absorption cross section for a 2D CFT. The entropies of the black holes are reproduced by the Cardy formula. |
