Hidden conformal symmetry of rotating charged black holes

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.Comment: minor changes, accepted versio

Holographic dual of linear dilaton black hole in Einstein-Maxwell-dilaton-axion gravity

“…Some related works on the hidden conformal symmetry of non-extremal black holes are listed in [43][44][45][46][47][48][49][50][51][52][53][54][55].…”

Hidden conformal symmetry of rotating black holes in the five-dimensional Gödel universe

“…Such a proposition was justified by the evidences that the CFT entropy via Cardy formula agrees with the macroscopic entropy through Bekenstein-Hawking area law and the absorption cross section for massless scalar in the near region can be interpreted as the one for a standard two dimensional finite temperature CFT. Some extensions of [51] appear in [52][53][54][55][56][57][58][59][60][61][62][63][64][65]. Calculations to real-time correlators [58,59] and extremal three-point functions of scalars in a generic non-extremal Kerr black hole [66] also provide evidences to the conjecture.…”

Hidden Conformal Symmetry of Extremal Linear Dilaton Black Hole in EMDA Theory

“…This result indicate that non-extremal Kerr black hole is holographically dual to a two-dimensional conformal field theory with non-zero left and right temperatures. The study of hidden conformal symmetry has been generalized to other kinds of black holes and turn out to be effective [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. But the conformal coordinates used in [18] dose not work in the extreme case.…”
