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

Abstract

We study the hidden conformal symmetry of extremal linear Einstein-Maxwelldilaton-axion black hole. After introduced a new set of conformal coordinates we find that if focusing on the near-horizon region, for the massless scalar scattering in the low-frequency limit, there exists hidden conformal symmetry on the solution space, and the real-time correlator is also agree with the conformal fields theory expectations.
